Idk but give me brainliest it will give you points back
Lets change "16" by its to 16/1 .. since nothing can't help support 16 by itself when it is going into 7/10
Now that we change that ... your problem becomes 7/10 × 16/1
7/10 × 16/1 = 11 1/5
Because
7(16) / 10(1) = 112/10
Now lets go. to how we solve the for the answer
112/10 = 11 1/5
