the only thing you need to do is separate m:
2/7m= 3/14 + 1/7
2/7m= 5/14
m= (5/14)/(2/7)
m= 5/14 × 7/2
m= 35/28
m= 5/4
70, because 528 divides by 264 is 2, which means each picture is 2 megabytes, so therefore 35x2 = 70
B is the correct answer ,,,
13.4 = 13.40
This is because the 0 at the end is a trailing decimal, and so when testing for inequalities, you can simply disregard it.
