Question 2.

Pedro is building a spice rack with 4 shelves that are each 0.55 meter long. At the hardware store, Pedro finds that he can only buy the shelving in whole meter lengths. Exactly how many meters of shelving does Pedro need? Since he can only buy whole-number lengths, how many meters of shelving should he buy? Justify your thinking.

Answer:- Pedro wants 4 x 0.55m = 2.20m of shelving. But the hardware store provide the shelving meters only in whole numbers so he have to buy

the shelving in whole number and i.e., 3m because 2.20 is very nearest to the whole number of 3m. So, he can buy the shelving in 3m.

Question 3.

Marcel rides his bicycle to school and back on Tuesdays and Thursdays. He lives 3.62 kilometers away from school. Marcel’s gym teacher wants to know about how many kilometers he bikes in a week. Marcel’s math teacher wants to know exactly how many kilometers he bikes in a week. What should Marcel tell each teacher? Show your work.

Answer:- Marcel says, He bikes in a week was 14km. Actual was 14.48km but he says approximate and nearest tenth of 14.48 km. Why because Marcel rides his bicycle to school and back on Tuesdays and Thursdays for to and fro 3.62 x 4 = 14.48km.

Question 4.

The poetry club had its first bake sale, and they made $79.35. The club members are planning to have 4 more bake sales. Leslie said, “If we make the same amount at each bake sale, we’ll earn $3,967.50.” Peggy said, “No way, Leslie! We’ll earn $396.75 after five bake sales.” Use estimation to help Peggy explain why Leslie’s reasoning is inaccurate. Show your reasoning using words, numbers, or pictures.

Answer:- The poetry club had its first bake sale, and they made $79.35 we will take a nearest whole number $80.00 this is for one bake sale. If they keep

four more bake sales and gets same sale as 80.00 they will earn 80 x 5 = 400 or $79.35 x 5 = $396.75. Leslie was wrong because she had multiplied 79.35

with 50 means with 50 bake sales not with 5 bake sales.
