Zahir completes 1/5 of his homework in 5/15 of an hour. How much time will
kogti [31]

Answer:

t = 100 minutes, or 1 hr, 40 minutes

Step-by-step explanation:

5/15 of 1 hour is the same as 5/15 of 60 minutes, which is 20 minutes

you can set up a proportion of hw completed / minutes = hw completed / min:

(1/5 ÷ 20) = (1 ÷ t)    we use '1' to indicate all homework (or 100% of hw) and 't' to indicate time required

cross-multiply to get:

20 = 5/t

t = 100 minutes, or 1 hr, 40 minutes

1. If there is a decrease of 31 percent, what decimal do we multiply by to get the amount after the decrease?
sdas [7]

answer

1.

Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

2.

Your measure start at 16. So that is the basis (unless stated otherwise) upon which you reference the change.

That is:

16

20−16

is you fraction.

This gives:

16

4

→

16÷4

4÷4

=

4

1

For this to be a percentage we need the denominator such that it becomes 100. Thus we have:

4

1

→(

4

1

×1)→(

4

1

×

25

)=

100

25

To express this in the standard script form we have 25%
