Hi

                   

+%283%2F5%29%2835kg%29+=+3%2835%2F5%29kg+=+3%2A7kg = 21kg

%281%2F4%29%287.2km%29 = 1.8km       7.2 ÷ 4 = 1.8

+%287%2F10%29%28R120%29=+7R%28120%2F10%29 = R84        120 ÷ 10 = 12,  7 times 12 = 84

+%283%2F8%29%2856kl%29=+3%2856%2F8%29kl = 21kl         56 ÷ 8 = 7,   3 times 7 = 21

+%284%2F5%29%2845m%29=+4%2845%2F5%29m = 36m            45 ÷5 = 9,   4 times 9 = 36
