The sum is 60 2/4 or when reduced completely it is 60 1/2

When adding mixed fractions add the whole numbers together normally. Then, if the denominators (the bottom number) of both fractions are equal you can add the numerators (top number) together normally. The denominators stay the same in addition for the answer unless it is like this case and the answer can be reduced

Hope this helped!

Answer:

Number of high quality version downloads = 880

Step-by-step explanation:

Let,

x be the number of standard version songs downloaded

y be the number of high quality version songs downloaded

According to given statement,

x+y=1600 Eqn 1

2.8x+4.1y=5624 Eqn 2

Multiplying Eqn 1 by 2.8 to eliminate x

2.8(x+y=1600)

2.8x+2.8y=4480 Eqn 3

Subtracting Eqn 3 from Eqn 2

(2.8x+4.1y)-(2.8x+2.8y)=5624-4480

2.8x+4.1y-2.8x-2.8y=1144

1.3y=1144

Dividing both sides by 1.3

$\frac{1.3y}{1.3}=\frac{1144}{1.3}\\y=880$

Hence,

Number of high quality version downloads = 880
