I need help with this question simplify 11/10 divide 1/5-6/3*4/7=

Oct 23rd, 2014

(11/10 ÷  1/5)  -  (6/3 × 4/7)    I have added brackets to show division and multiplication must be done before subtraction

=(11/10 ×  5/1) -  (6/3 × 4/7)   change division to multiplication and 6/3 = 6 ÷ 3 = 2

= 55/10 - 24/21   

= 11/2 - 8/7        cancelling by 5 and 7

= 77/14 - 16/14   multiplying the first fraction by 7 and the second by 2 to get same denominator of 14

= 61/14

=4 5/14          dividing 61 by 14 gives 4 remainder 5
