What is a two digit number that is one third of the number is 7 more than one fourth of the number and the first digit is twice the second digit and the sum of the digits is a two digit number?
2.3
How do you decide if a two-digit number is a multiple of a one digit number?
Divide the 2-digit number by the 1-digit number. If the quotient comes out a whole number, then the big one is a multiple of the small one.
You are a five digit number your digits increase in size from the left Each digit is different your first and fifth digits are square numbers your first and fourth digits are cubed numbers your 2nd?
There are a lot of possibilities. The second digit can be 2 through 6, the third digit can be 3 through 7 as long as it is larger than the second digit. What we have so far: 1 _ _ 89
How does the divisibility rule for 4 and 8 work?
A number is a multiple of 4 if the last 2 digits are a multiple of 4 The 10s digit is even and the last digit is 0, 4 or 8 The 10s digit is odd and the last digit is 2 or 6 A number is a multiple of 8 if the last 3 digits are a multiple of 8 The 100s digit is even and the last 2 digits are a multiple of 8 The 100s digit is odd and the last 2 digits are 4 times an odd number
Use the make a ten strategy to find the sums and differences 89 plus 24 Change one number to a multiple of 10?
89+24 change one number to a multiple of ten 90 is closest to 89 and you added by one digit adjust the other number (drop the second number by the same digit as the first number adjusted (one digit). 23 90+23=113 89+24=113
