Add. reduce to lowest terms. 6 4/5 + 3 7/10 =

10  1/2

Step-by-step explanation:

The LCD here is 10.

Thus, our  6 4/5 + 3 7/10  becomes 6  8/10 + 3  7/10.

Adding the whole numbers, we get 9; adding the fractions, we get 15/10, or 1 1/2.  Combine this 9 and this 1  1/2:

Thus, our  6 4/5 + 3 7/10 becomes 10  1/2.

the answer is 4.8 units on e2020.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
