Question

Teddy worked 10 out of the 14 days. At this rate, how many days will he
work in 49 days?​

Answer 1

35 days

Explanation:

All you need to do is find a fraction that is proportional to the first, with a denominator of 49:

`(10)/(14) = (x)/(49)`

So you all you do is move the 49 to the other side of the equation. How do you do this? Multiply both sides by 49 (cross multiply):

`(10*49)/(14)=(x*49)/(49)`

`(490)/(14)=x`

`35=x`

So Teddy will work 35 days out of 49 days.
