Raphael had 5 hits in 7 at bats. If he continues this pattern, how many hits will he have in 210 at bats?
devlian [24]

So it tell us that he is able to get 5 hits out of 7 and to find how much he could make if 210 chances
\frac{5}{7} = \frac{x}{210}

We solve what can be solved
0.7 = \frac{x}{210}

Then we leave our variable alone
0.7 *210=x

Last we solve
x=147

In this case we can see that he could make 147 hits out of 210 bats.

3/7 of x is 2-1/14.

x = (29/14) * (7/3)

x = (29/2) * (1/3)

x = 29/6

3/7 of 4 and 5/6 is 2 1/14.

Hope this helps!
