Question

What is 4/5 + 3/4 I need it for my homework

Answer 1

Answer:

4/5 + 3/4 = $1\frac{11}{20}$ or 1.55

Step-by-step explanation:

This can be solved by first finding the highest common factors of denominators of the two fractions, i.e. 4 and 5.

The highest common factor of 4 and 5 can be found by multiplying the two numbers as follows:

The highest common factor of 4 and 5 = 4 * 5 = 20

This can now be used to solve  4/5 + 3/4 as follows:

4/5 + 3/4 = ((4 * 4) + (5 * 3)) / 20 = (16 + 15) / 20 = 31 / 20 = $1\frac{11}{20}$ or 1.55

Therefore, we have:

4/5 + 3/4 = $1\frac{11}{20}$ or 1.55
