13, because 78 postcards divided by 6 cards per board = 13 poster boards
1) Would be c+15 because you can combine 19-4
2) Would be m+2 because you can combine 12-10
2/9=22%
21%
21%
22%
So it would be 21%, 0.21, 11/50, 2/9.
Answer:
5,800m
Step-by-step explanation:
1 km = 1000 m
Use the SBD (small to big, divide) and BSM (big to small, multiply) method.
So, 5.8 X 1000, as we are converting km(big) to m(small) and move the decimal point corresponding to the number of zeroes = 5800m
