Answer:
1 4/19
Step-by-step explanation:
15 into 19 is 1 r4 and as a mixed number its 1 4/19.......
I might be wrong but that's what i got!
1 time, unless in decimal form which is 1.266666666(infinite)66666667
15x1=15
15x2=30
30 is too high, so 15 is the only option.
i'm not too good in this, but i believe the answer is -3
the hcf, highest common factor, of both -3 and -15 is -3, hence making the answer -3? if this is incorrect, i apologize.
hope my answer will help you
