Question 10 Using the digits 2, 4, 5, 8, and 0 fill the boxes to get the: (a) maximum product To get the largest product, we put the largest digits in the highest place values (the tens and the ones). So, our solution is 𝟖𝟐.𝟎 × 𝟓.𝟒=442.8 Question 10 Using the digits 2, 4, 5, 8, and 0 fill the boxes to get the: (b) minimum product To get the smallest product, we use the smallest digits in the highest places, and if possible, use 0 to keep the multiplier small. So, our solution is 𝟒𝟓.𝟖 × 𝟎.𝟐=9.16 Question 10 Using the digits 2, 4, 5, 8, and 0 fill the boxes to get the: (c) product greater than 150There are many answers; here is one: 24.5 × 8.0=𝟏𝟗𝟔 Question 10 Using the digits 2, 4, 5, 8, and 0 fill the boxes to get the: (d) product nearest to 100We look for a combination that gets as close to 100 as possible. So, our solution is 20.5 × 4.8=𝟗𝟖.𝟒 (This is only 1.6 away from 100). Question 10 Using the digits 2, 4, 5, 8, and 0 fill the boxes to get the: (e) product nearest to 5Since our minimum product is already 9.16 , that is the closest we can get. So, our solution is 45.8 × 0.2=𝟗.𝟏𝟔
