The speaker is demonstrating what an adult helping children does. What does an adult do to
help children manage their reading?
Solution:
2 fifths of 20-cent coins + 3 sevenths of 50-cent coins 39 coins
4 fifths of 20-cent coins + 6 sevenths of 50-cent coins 2 x 39 coins = 78 coins
1 fifth of 20-cent coins + 1 sevenths of 50-cent coins 94 – 78 = 16
5 fifths of 20-cent coins + 5 sevenths of 50-cent coins 5 x 16 = 80
2 sevenths of 50-cent coins 94 – 80 = 14
There are 14 2 x 7 = 49 fifty-cent coins.
There are 94 – 49 = 45 twenty-cent coins.
Sally had 49 x 50 cents + 45 x 20 cents or $33.50.
Answer:$33.50
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16
?
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16
?
94 – 2 x 39 = 94 – 78 = 14 + 2 = 16
39 – 2 x 16 = 39 – 32 = 7
How many 50-cent coins?How many 20-cent coins?
Solution:
(a)(3m + 6) cm
(b) length = 3 x 4 cm + 6 cm = 18 cm and width = 3 cm
area = 18 cm x 3 cm = 54 cm2
