Question

1. What two 1-digit factors could you multiply to get a product between and including 40 and 50?

2. A pound of Guinea pig pellets is about 3 cups of food. Each Guinea pig eats 1/4 cup of pellets a day. How many days will the pellets last? Explain.

( There are 2 Guinea pigs)

Answer 1

9×5 are 45

12 days.....

Answer 2

1. We need to find two 1-digit factors that are multiplied to get a product between 40 and 50

So, let us first take one factor to be 5

Now, to make its product with the second factor between 40 an d 50, we take second factor to be 9

Now, 9 × 5 = 45

And, 40 ≤ 45 ≤ 50

Hence, The required two 1-digit factors are : 5 and 9

2. Number of Guinea pigs = 2

`\text{Each Guinea pig eats }(1)/(4)\text{ cup of pellets a day}`

`\text{Hence, fraction of cup eaten by 2 Guinea pigs a day = }(1)/(4)* 2=(1)/(2)`

A pound of Guinea pig pellets is about 3 cups of food

`\bf\textbf{Number of days the pellets will last = }(3)/((1)/(2))\\\\=3* 2\\\\=6\:\:days`
