Answer:
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
\(\text{Each Guinea pig eats }\frac{1}{4}\text{ cup of pellets a day}\)
\(\text{Hence, fraction of cup eaten by 2 Guinea pigs a day = }\frac{1}{4}\times 2=\frac{1}{2}\)
A pound of Guinea pig pellets is about 3 cups of food
\(\bf\textbf{Number of days the pellets will last = }\frac{3}{\frac{1}{2}}\\\\=3\times 2\\\\=6\:\:days\)
