Question

Explain how you could use the strategy solve a simpler problem to solve the equation 3/4x=3/10

Answer 1

0.4

Explanation:

Answer 2

x = 0.4

Explanation:

Let me rewrite it so it looks better:

`(3)/(4) x=(3)/(10)`

The first way is to cross multiply.

30x = 12

x=0.4

The other way is to see that the two numerators are the same except for the x on the left side.

You can see the the denominators are 4 and 10.

You can create a proportion of 4 : 10 and apply it to the fractions.

You get that you have to multiply the left side by 0.4, so x = 0.4
