Answer:

i got 70

Step-by-step explanation:

Brain 4 Brain gets 42 more sweets Sara

Pip 5 How many sweets does Pip get?

Sara 1

when b = s + 42 find p b = 4s p = 5s

4s = s + 42 b/4 = s p = 5b/4

3s = 42

s = 14 b = 56 p = 70

I initially found the answer by trail and error, then I could figure out the equation.

s b p

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.
