Camille found the sum of 3 4 and 5 8 by following these steps: step 1: the least common denominator is 8. step 2: 3 4 + 5 8 = 7 8 + 5 8 step 3: 7 8 + 5 8 = 12 8 step 4: 12 8 = 1 4 8 = 1 1 2 determine whether camille's work is correct. if not, which step has an error?

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

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.
