One number is 3/8 of another number. The difference of the two numbers is 4.2. What is the lesser number
boyakko [2]

Answer:

2.52.

Step-by-step explanation:

If one number is x then the other = 3x/8.

Also x - 3x / 8 = 4.2

x - 0.375 x = 4.2

0.625x = 4.2

x = 4.2 / 0.625

x = 6.72.

So the lesser number is 6.72 * 0.375 = 2.52.

A pie has been in the oven for some number of minutes. it needs to bake for a total of 60 minutes. for how many more minutes mus
Lesechka [4]

The pie must stay for 60 - x more minutes must the pie bake

<h3>For how many more minutes must the pie bake?</h3>

Let the amount of time spent in the oven be x

So, we have

Total amount of time = 60 minutes

This means that

Remaining time + Amount of time spent = 60

This gives

Remaining time + x = 60

Evaluate

Remaining time = 60 - x

Hence, the pie must stay for 60 - x more minutes must the pie bake

Dominik [7]

" 100% " means "the whole thing",
and "is" can be replaced by "is equal to".

You have said "The whole thing of a number is equal to 61."
or
                       "61 is equal to the whole thing of a number."

The only number that 61 can be equal to is 61.
