Question

3/4 - 3/10 = ? need in simplest form

Answer 1

9/20

Answer 2

find a common denominator. The least common multiple is 20. So multiply 3/4 with 5 and 3/10 with 2. So it would become 15/20 - 6/20. 15- 6= 9. so the answer is 9/20

Answer 3

ok 3/4 - 3/10=0.45 and 0.45 in simplest form is 45/100 which changes to 9/20

Answer 4

4/7 - 2/5 = ? simplest form

Answer 5

find a common denominator once again. The least common denominator is 35. So multiply 4/7 with 5 and 2/5 with 7. This becomes 20/35 - 14/ 35. So the answer is 6/ 35.
