1. One third of the animals in the barn are chickens. The rest are pigs.

There are 20 legs in all.

How many pigs are there? There are four pigs.

If ⅓ are chickens then ⅔ are pigs. Each chicken has two legs and each pig has four legs.

2. I have three dogs of different ages.

If I add their ages together I get 15.

If I multiply their ages together I get 45.

How old are my dogs? The dogs ages are 1, 5, and 9

Because 1+5+9=15 and 9x5x1=45

3. Niko and Kaia buy their father a card for Fathers’ Day.

The card costs $5.90. Niko puts

in 40c more than Kaia.

How much do they each contribute

to the card?

Half of $5.90 is $2.95 Niko put 40c more

so Niko payed $3.15 and Kaia payed $2.75

4. I think that you’ll find a pattern in the numbers below.

8 x 8 + 13 =77

88 x 8 + 13 =717

888 x 8 + 13 =7117

8888 x 8 + 13 =71117

88888 x 8 + 13 =711117

Does the pattern extend indefinitely?

Yes Because 88888888888x8+13=

711111111117
