Question

Tuesday he used 3/5 as many of 1/8

Answer 1

`(3)/(5) - (1)/(8) = (19)/(40)`

TOTAL:

=0.475

Explanation:

3/5 - 1/8 = 3.8/5.8 - 1.5/8.5 = 24/40

- 5/40 = 24-5/40 - 24-6/40 =19/40

✿For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 8) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 8 = 40. In the following intermediate step, it cannot further simplify the fraction result by canceling.

Answer 2

19/40 = 0.475 You can use either the fraction or the decimal

Explanation:

3/5 - 1/8 = 3 · 8/5 · 8 - 1 · 5/8 · 5 = 24/40 - 5/40 = 24 - 5/40 = 19/40
