8) jaspreet travelled 20 2/5 km by car = 102/5 km
jaspreet travelled 10 1/4 km by bus = 41/4
total distance covered by her = 102/5 + 41/4 = 613/20 = 3 15/20 km
9) cups of milk needed = 2 3/4 = 11/4
cups of cream needed = 1 2/3 = 5/3
lcm of 4 and 3 = 12
cups of milk needed = 33/12
cups of cream needed = 20/12
therefore, cream is needed in more quantity
cups of cream needed in more quantity= 33/12 - 20/12 = 13/12 = 1 1/12
10) 3 2/5 = 17/5
2 2/3 = 8/3
19/6
4 1/2 = 9/2
lcm of 5, 3, 6, 2 = 30
17/5 = 102/30
8/3 = 80/30
19/6 = 95/30
9/2 = 135/30
greatest fraction = 135/30
smallest fraction= 80/30
greatest fraction- smallest fraction = 135/30 - 80/30 = 55/30 = 11/6 = 1 5/6
hope my answer helps you!
