After saving 2/7 of his paycheck for the month, mr. donovan has $1,335 left to spend. mrs. spencer saves 3/8 of her paycheck. both of them save the same amount of money. how much is mrs. spencers paycheck?

Given:
Mr. Donovan
2/7 = savings
5/7 = $1,335

Mrs. Spencer
3/8 = savings

Both saved the same amount of money. How much is Mrs. Spencer's paycheck?

Mr. Donovan's paycheck.
1,335 ÷ 5/7 = 1,335 * 7/5 = 9345/5 = 1869

Mr.Donovan's savings
1869 * 2/7 = (1869*2)/7 = 3738/7 = 534

Mr. Donovan's savings = Mrs. Spencer's savings

Mrs. Spencer's pay check
534 ÷ 3/8 = 534 * 8/3 = 4272/3 = 1424

Mrs. Spencer's paycheck is $1,424

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
