口 - 6+2+1+10+10+10+10+2+10

49

Step-by-step explanation:

- 6+2+1+10+10+10+10+2+10

so lets add from the start . . .

-6+2=-4

-4+1+10+10+10+10+2+10

then slowly work your way through the problem

-4+1=-3

-3+10+10+10+10+2+10

-3+10=7

7+10+10+10+2+10

you could do it the standard way of 7+10+10+10+2+10

but since there are 4 tens left . . . you can do 7+2+ 10(4)

9+40

answer is 49

hope this helps and please mark me brainliest!

207/8 is the right

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
