Let the 3 digit number be 393
one of the digit is 9
Let the other addend be 2 digit number that is 20
393 + 20 = 413

Question 7.
Find the difference.
326 – 174 = _________

Explanation:
Put the 2 in one’s place and carry ‘-‘ to the carry row
Put the 5 in ten’s place and carry 12 to the carry row
Put the 1 in hundred’s place and carry 2 to the carry row
Therefore, the final result of subtraction between given two numbers, 326 and 174 using the long subtraction method is 152

Question 8.
Which is the difference?

Question 10.
Lois has 18 beads. She uses 6 beads to make each necklace. She sells each necklace for $10. How much money does Lois make? Write two equations to model and solve the problem. Use letters for the unknown quantities. Answer:$30 that Lois have
Explanation:
Lois has 18 beads. She uses 6 beads to make each necklace.
Let n be the number of beads
18 ÷ 6 = n
n = 3
She sells each necklace for \$10.
let t be the total money
3 x 10 = t
t = 30
