Answer: see picture at the bottom
Step-by-step explanation:
To get the third blank, you know that 9*6=54, so take the last digit (4) and put that in the third blank = 4
Then x * 6 = 144
x = 19, so the first blank is 1
then a number times 9 has a last digit of 6, and you know that 9 * 4 = 36, so the second blank is 4
19 * 4 = 76 so the fourth blank is 7
1 + 6 = 7 so the sixth blank is 7
1 + 7 = 8 so the fifth blank is 8
on the second problem
4 * 3 = 12 so the third blank is 2
102/4 = 34 so the first blank is 3
a number times 4 has a last digit of 8 and we know that 4 * 2 = 8 so the second blank is 2
2 * 34 = 68 so the fourth blank is 6
1 + 6 = 7 so the fifth blank is 7
0 + 8 = 8 so the sixth blank is 8
