Question

an electrician needs to buy 61 light bulbs. the light bulbs come in packages of 7. how many packages should the electrician buy? packages submit

Explanation:

Step1: Divide the total number of bulbs by bulbs per package

$$61\div7 = 8\frac{5}{7}$$

Step2: Consider the practical situation

Since we can't buy a fraction of a package and \(8\) packages will give \(8\times7 = 56\) bulbs (which is less than \(61\)), we need to round up.

Answer:

\(9\)
