To find out how many cattle Mrs. Metcalf has, we can use the information given in the problem:
Mr. Ford has 78 cattle, which is 3 times the number of cattle Mrs. Metcalf has. We can express this relationship with the equation:
\[ 78 = 3c \]
To solve for \( c \) (the number of cattle Mrs. Metcalf has), we need to divide both sides of the equation by 3:
\[ c = \frac{78}{3} \]
Now, let's perform the division:
\[ c = 26 \]
So, the answers to complete the sentences are:
- c = 26
- Choose ÷ 3 (since we are dividing by 3 to find c)
- Choose 78 (as that is the number of cattle Mr. Ford has)
In summary, Mrs. Metcalf has 26 cattle.
