An electrician can wire on average 4.5 houses in a week. how many months will it take her to wire 55 houses if she wires the same number each week and figures on 4.5 weeks per months?

If you know how to divide by decimal you have to divide 55 ÷ 4.5 and you would get 12 but if you don't know keep multipling a number times 4.5 but overall if you don't want to do all the work the answer is going to be (55×4.5=12 or 4.5×12=55— 12 houses)

4.5 x 10 = 45

4.5 x 2 = 9

9 + 45 = 54

54 + 4.5 = 58.5

1 + 2 + 10 = 13 weeks

13.5 weeks = 3 months

2 months and 4 weeks
