Subject: Mathematics

Topic: Fractions and Decimals

Content

Ordering of fractions

Which is larger  35 or 12 ?

L.C.M of 5 and 2 is 10

35 = 3 X 25 X 2 = 610, 12 = 1 X 52 X5 = 510

Since 6 > 5, therefore 610 > 510

35 > 12

Thus, 35 is larger

Which is smaller 59 or 815

L.C.M of 9 and 15 = 45

59 = 5 X 59 X 5 = 2545, 815 = 8 X 315 X 3 = 2445

Since 24 < 25, therefore 2445 > 2545

Thus 815 is smaller

Using fractions in sharing

13 of 60 oranges are shared. Find the number oranges shared

13 of 60 = 603 = 20

Therefore, 20 oranges are shared
