### Jenna's first growing post

Which set of fractions is larger 1/2 + 1/6 or 1/4 + 7/12 ?

1/2 + 1/6 = 40/60 or 4/6
1/2 = 60 / 2 = 30
1/6 = 60 / 6 = 10
30+10 = 40

1/4 + 7/12 = 50/60 or 5/6
1/4 = 60 / 4 = 15
7/12 = 60 / 12 = 5 x 7 = 35
15+35= 50

1/2 + 1/6 < 1/4 + 7/12

Jenna and Anne's bikerace

Anne and I calculated the Km positions at a twelfth, sixth and a third by counting. We counted by 3's until we got to 60. Then we counted by 6ths then 12ths, But we did it wrong.

2 different ways to find a quarter and 3/4 of a number is division and cutting in half.

DIVISION

to find 1/4 of 22 you have to divide 22 by 4, which equals 5.5 . So 1/4 of 22= 5.5 , To find 3/4 of 22 you have to divide 22 by 4 again but this time multiply it by 3 and it equals 16.5

CUTTING IN HALF

to find 1/4 of 22 you cut it in half 2 times. So half of 22 is 11 and half of 11 is 5.5 , To find 3/4 of 22 you have to cut it in half 2 times again then just multiply by 3

FRACTION GAME

On this website there are two games . They are both about comparing fractions. The first game is a dolphin race. You have to chose the largest fraction to win. The second game is ordering fractions . You have to put the fractions in order from largest to smallest. I think this game is helpful because it teaches you which fractions are bigger.

My Fraction Question: which is larger? 2/4+3/6 or 1/3+6/12
