Ron had 20 apples. He used 2/5 of the apples to make pies. How many apples did Ron use for pies?

Answers

Answer 1

Answer: 1/5 of 20 is 4.

2/5 of 20 is 8.

Therefore, Ron used 8 apples to make his pies.

Answer 2

Answer: Ron used 8 apples for his pies. 20/5=4 so 4 times 5 equals 20 and if you multply by 4 on one side you have to multiply by 4 on the other. And 4 times 2 equals 8.

24 written as a percentage

Answers

Any number is equal to that number over 1

So x is equal to x/1

Same thing with 24. 24 = 24/1

To get it into percent we multiply by 100 so:

$\sf{(24)/(1)=(24*100)/(1*100)}$

And simplifying that we get

$\sf{(2400)/(100)}$

And x/100 = x%

so 2400/100 = 2400%

So your answer is 2400% :)

write two mixed numbers that have a sum of 3

Answers

1 1/4 + 1 3/4 = 3.

That's because 1/4 + 3/4 = 4/4, which equals 1.

1 + 1 = 2.

Now add the 1 from the 4/4 to the 2, and you get 3.

one would be 1 1/2 + 1 1/2
hope that helps you finish your homework! :)

What is the ratio of the total number of baked goods to cobblers in simplest form?

Answers

Q1. The answer is d) 13 to 18

There are 13 pens and 18 pencils. Ratio of pens to pencils can be written as:
pens : pencils

Since pens = 13 and pencils = 18, then
pens : pencils = 13 : 18

Or in other words, ratio of pens to pencils is 13 to 18. Thus, choice d) is correct.

Q2. The answer is C.5 to 8

There are 12 tulips and 20 roses. The total number of flowers is 12 tulips + 20 roses = 32 flowers. Ratio of roses to the total number of flowers can be written as:
roses : total flowers

Since roses = 20 and total flowers = 32, then
roses : total flowers = 20 : 32

Now, let's simplify 20 to 32 ratio:
20 : 32 = (20 / 4) : (32 / 4) = 5 : 8

Or in other words, ratio of roses to the total number of flowers is is 5 to 8. Thus, choice C. is correct.

Q3. The answer is 3 : 4

There are 30 one-story homes and 24 two-story homes. Ratio of two -story homes to one-story homes can be written as:
two-story homes : one-story homes

Since one-story homes = 32 and two-story homes = 24, then
two-story homes : one-story homes = 24 : 32

Now, let's simplify 24 to 32 ratio:
24 : 32 = (24 / 8) : (32 / 8) = 3 : 4

So, the ratio of one-story homes to two-story homes is 3 to 4.

Q4. The answer is

There are 16 trading cards and 2 wildlife cards. Ratio of wildlife cards to total trading cards can be written as:
wildlife cards : trading cards

Since trading cards = 16 and wildlife cards = 2, then
wildlife cards : trading cards = 2 : 16

Now, let's simplify 2 to 16 ratio:
2 : 16 = (2 / 2) : (16 / 2) = 1 : 8

So, the ratio of wildlife cards to total trading cards is 1 : 8

Q5. The answer is

There are 3 cobblers. The total number of baked goods is 12 cookies + 9 pies + 8 cakes + 4 tarts + 3 cobblers = 36 baked goods. Ratio of the total number of baked goods to cobblers can be written as:
baked goods : cobblers

Since baked goods = 36 and cobblers = 3, then
wildlife cards : trading cards = 36 : 3

Now, let's simplify 36 to 3 ratio:
36 : 3 = (36 / 3) : (3 / 3) = 12 : 1

So, the ratio of the total number of baked goods to cobblers is 12 : 1

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9. Write the division problem that Martin solved

Answers

Answer:

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$

Step-by-step explanation:

Consider the provided information.

Martin chose two of the cards below. When he found the quotient of the numbers, his answer was -16/9.

As we know that the quotient of the number is a negative number.

Therefore, the sign of both numbers must be different,

Thus we can concluded he must select $(2)/(3)$ as one of the card, so that product is a negative number.

Let the selected card be x.

$(2)/(3) / x =(-16)/(9)\n\nx=(2)/(3)/(-16)/(9)\n\nx=(2)/(3)*(-9)/(16)\n\nx=(-3)/(8)$

Hence, the two cards should be $(2)/(3)$ and $(-3)/(8)$

The required division problem he must solve is:

$(2)/(3) / (-3)/(8) =(2)/(3)*(-8)/(3)=(-16)/(9)$
