Question

Simplify: `5 3/4 - 3/7 xx 15 3/4 + 2 2/35 div 1 11/25`

Answer 1

Convert all mixed numbers into improper fractions

`5 3/4 = (5 xx 4 + 3)/4 = 23/4`

`15 3/4 = (15xx4+3)/4 = 63/4`

`2 2/35 = (2xx35+2)/35 = 72/35`

`1 11/25 = (1xx25+11)/25 = 36/25`

`23/4 - 3/7 xx 63/4 + 72/35 ÷ 36/25`

`3/7_1 xx 63^9/4 = (3xx9)/4 = 2/4`

`23/4 - 27/4 + 72/35 div 36/25`

`72/35 xx 25/36`

`72^2/35_7 xx 25^5/36_1 = (2xx5)/7 = 10/7`

`23/4 - 27/4 + 10/7`

`23/4 - 27/4 = (23-27)/4 = -4/4 = -1`

`-1 + 10/7 = -7/7 + 10/7 = (-7+10)/7 = 3/7`

`= 3/7`
