so assuming you mean number 17 so
part A
graph has 3 buttons of 1/16, 3 buton of 1/8, and 3 buttons of 1/4
add them
3 times 1/16+3 times 1/8+3 times 1/4
3/16+3/8+3/4
make bottom nubmer the same
3/16
3/8 times 2/2=6/16
3/4 times 4/4=12/16
3/16+6/16+12/16=21/16=1 and 5/16 inch high
answer is 1 and 5/16 inch high
part B
so she has 1 and 5/16 high
she wants it to be 2 high
subtract to find difference
2-1 and 5/16=(1-1)+(1-5/16)=0+1-5/16=16/16-5/16=11/16
how many 1/16 butttons does it take to make 11/16
duh 11
the answe ris 11 1/16 buttons
