Riley adds 45.3 and 3.21 should his sum be greater than or less than 48 tell how you know

Answers

Answer 1
Answer:
His sum should be more than 48.

I know because if you throw away the decimal pieces
and just add up the whole numbers  45  and  3 ,
right there you would have 48 .  So when you include
the decimal pieces, they'll make it even bigger.
Answer 2
Answer: From it saying Riley ADDS you know its subtracting, so add 45.3 and 3.21 together. 
Which is 48.51, so it is greater then 48.

Emma has 18 yellow flowers and 30 white flowers.She wants to split them into vases in equal groups.What is the largest number of groups she can make?

Answers

Keywords:

Flowers, yellow flowers, white flowers, group, GCF

For this case we have 18 yellow flowers and 30 white flowers, we must find a number that represents the largest number of groups of flowers that can be formed, bearing in mind that each group must contain the same number of yellow and white flowers. To do this, we must find the GCF (Greatest Common Factor) of yellow flowers and white flowers.

We look for the factors of 18, that is, the numbers for which 18 is divisible, these are:

18, 9, 6, 3, 2 and 1

We look for the factors of 30, that is, the numbers for which 30 is divisible, these are:

30, 15, 10, 6, 5, 3, 2, 1

Thus, we can see that GCF of both numbers is 6.

Then we can form 6 groups of flowers. To know the amount of flowers of each color in each group, we divide:

Yellow\ flowers = \frac {18} {6} = 3\nWhite\ flowers = \frac {30} {6} = 5

Thus, 6 groups of flowers can be formed with 3 yellow flowers and 5 white flowers each.

Answer:

The largest number of groups that can be done is 6.

Answer:

She can make 6 number of group.

Step-by-step explanation:

Given : Emma has 18 yellow flowers and 30 white flowers.

To find  : What is the largest number of groups she can make.

Solution:We have given that

yellow flower = 18

White flower = 30

we nee to find the GCF (Greatest Common Factor) of yellow flowers and white flowers.

Factors of 18 are:

18, 9, 6, 3, 2 and 1

Factors of 30 are:

30, 15, 10, 6, 5, 3, 2, 1

Thus, we can see that GCF of both numbers is 6.

Then we can form 6 groups of flowers.

Thus, 6 groups of flowers can be formed with 3 yellow flowers and 5 white flowers each.

Yellow flower = (18)/(6) = 3

White flower = (30)/(6) = 5

Therefore, She can make 6 number of group.

Ten pounds of rice are distributed equally into 6 bags to give out at the food bank. How many pounds of rice are in each bag?

Answers

its simple just divide the total of pounds by the total of bags;
10 lb of rice ÷ 6 bags = 1.67 lb (rounded to the nearest hundredth)
so there's 6 bags with 1.67 pounds each.

70.443+4.885*2.6-16 rounded to the nearest interger

Answers

you use PEMDAS

4.885*2.6=12.701

12.701+70.443=83.144

83.144-16=67.144

and now you can round since the decimal is smaller than 0.500 you round down getting the answer of 67
