10 people who build at the same rate can frame a house in 6 days. What fractional part of a house can 4 people frame a house in 3 days?a. 1/2
b. 1/3
c. 1/4
d. 1/5
e. 1/6

Answers

Answer 1
Answer:

10 people who build at the same rate can frame a house in 6 days. That means it will take one person 10*6=60 days to finish the house.

Which means that it will take 4 people (60)/(4)=15 days to finish the house.

So, the fractional part of the house 4 people can frame in 3 days will be (3)/(15)=(1)/(5)

Thus, OptionD is the correct answer.

40% of what number is 5

Answers

40% can be expressed as 40/100 or 0.4

(40)/(100) * x = 5\n\n0.4 * x = 5

Divide both sides by 0.4 to isolate 'x'

0.4x = 5\n\n(0.4x)/(0.4) = (5)/(0.4)\n\nx = (5)/(0.4) \n\n\boxed{\bf{x = 12.5}}

40% of 12.5 is 5.
It would be 12 and 1/2 because 40% is 2 and 1/2 of 100 and then you do 5 times 2 and 1/2 and you get 12 and 1/2.

Answers

70×40=2800cm which is the total amount of cm that the teacher needs

10m = 1000cm 

(2800)/(1000) = 2.8

there will be 3 balls of string
70×40=2800 cm, which would be the total amount of cm that the teacher needs for the balls.

10m = 1000cm 

 = 2.8

There will be 3 balls of string.

What is 1 and 3/4 + 1 and 5/8?

Answers

Answer:

3 3/8

Step-by-step explanation:

1  3/4 + 1 5/8

We need to get a common denominator of 8

1 3/4 *2/2  + 1 5/8

1 6/8  + 1 5/8

I like to line them up vertically

1  6/8

1  5/8

---------------

2 11/8

But 11 is larger than 8  so we subtract 8/8 and add 1

2 11/8

+1 -8/8
