Question

`(d)/(7) = 42`how do you solve a problem like this

Answer 1

We must solve the following equation:

`(d)/(7)=42`

1) Multiplying both sides of the equation by 7 we have:

`7\cdot(d)/(7)=7\cdot42`

2) Cancelling the 7 in the numerator and denominator on the left:

`d=7\cdot42=294`

Answer: d = 294
