Maths Mate Term 4 Sheet 5 Question 24

Fill in the missing digits, using the digits one to nine.

1  _  9

x      6

________

_   5   _

Answer:

 First I worked out that 6 times 9 is 54, so I put the 4 down in the unit column and carried the 5 to the next column.

Then I had to figure out 6 x ? plus the 5 carried over and the answer needed to end in 5. So I figured out that 6 x 5 is 30 and if I then add the carried 5 the answer is 35. The 5 is already in the answer so I just have to carry the 3 over to the next column.

Then I figured out that 6 x 1 plus the carried over 3 equals 9.

Therefore the solution to the problem looks like this :

355  9

x        6

________

9   5  4

 

 

9   5  4
