Salutations!

If seven pencils cost $.84 find the cost of 10 pencils?

Lets solve this!

To solve this question, you need to first divide .84 ÷ 7 which gives you the answer 0.12. Then multiply 0.12 with 10 which gives you the cost of 10 pencils. 0.12 is the cost of only one pencil.

Lets forms this into statements ---

Cost of 7 pencils = $ .84

Cost of 1 pencil = $ 0.12

Cost of 10 pencil equals = .84 ÷ 7 = 0.12

                                      = 0.12 × 10 = 1.2

Cost of 10 pencils is $1.2

Divide 7 pencils into $.84 to find out the cost of one.
Then multiply that number and 10
.84/7 = $.12
.12x10 = $1.20 for ten pencils.
