Answer as a mixed number: 13 19/60

=========================================================

Step-by-step explanation:

I'll be using this formula

a & b/c = (a*c+b)/c

to convert from a mixed number to an improper fraction

a & b/c = (a*c + b)/c

2 & 5/6 = (2*6 + 5)/6

2 & 5/6 = (12 + 5)/6

2 & 5/6 = 17/6

Use similar steps to find that

4 & 7/10 = 47/10

-------------------------

The picture is 17/6 inches tall. The length is 47/10 times this height value.

length = (47/10)*(height)

length = (47/10)*(17/6)

length = (47*17)/(10*6)

length = 799/60

------------------------

Then let's convert that to a mixed number.

Use a calculator to get 799/60 = 13.31667 approximately.

The stuff to the left of the decimal is the whole part 13, aka the quotient.

The remainder is calculated like so:

remainder = numerator - quotient*denominator

remainder = 799 - 13*60

remainder = 19

Therefore, 799/60 = 13 remainder 19

In other words, 799/60 = 13 & 19/60 which is equivalent to writing 13 19/60
