8.88 x 10,000 really confused with this one on my homework, can you guys anseer and explain why? would really help!
Answers
When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.
Because 10,000 has 5 0's, we move the decimal 5 places to the right.
8.88 => 88800

According to the data, 20 foot = 2.5 inches
if we want to find out the measurement for 1 foot, 2.5 inches has to be divided by 20. 1 foot = 2.5/20 = 0.125
If it is increased to 28 foot, answer should be multiplied by 28. 0.125*28 = 3.5 in
Answer c is correct
1 foot = 12 inches, but Scale = 2.5 inches : 20 feet = 1 inch : 8 feet
New size = 28 feet Therefore, Let the corresponding measurement be x inches. So, 1 : 8 = x : 28 1 x -- = ---- 8 28
