Find the greatest 2-digit number with 5 as factor Find the smallest 2-digit number with 7 as factor

Find the smallest 3-digit number with 3 as factor

Find the smallest 3-digit number with 11 as factor​

1. 95

2. 14

3. 102

4. 110

explanation:

1. In order to find the answer for number 1 we will have to count down from 99 because that is the greatest possible 2 digit number. We also know that a number that has a factor of 5 ends with a five, therefore 95 is the greatest two digit number with 5 as a factor.

2. now we have to start with 10 because that is the smallest 2 digit number and going up the 7 times table. 7 times 2 s 14 and that is the smallest two digit number.

3. since it says smallest 3 digit number we have to start at 100. 100 is not dividable with 3. 101 is not dividable by 3, but 102 is dividable by 3 making it the smallest three digit number.

4. again we have to start with 100. 11 times 10 is 110. 11 times 9 is 99 so we cant use 11 times 9. therefore 11 times 10 also know as 110 is the smallest three digit number.

Explanation:

Find the greatest 2-digit number with 5 as factor

95/5 = 19

95

Find the smallest 2-digit number with 7 as factor

14/2 = 7

7

Find the smallest 3-digit number with 3 as factor

999/3 = 333

999

Find the smallest 3-digit number with 11 as factor

100/1 = 100

100
