Answer:
The bold ones
Step-by-step explanation:
1, 1/2=2/4, 2/4+(-1/4)= 1/4
2, -10.28+(-5.34)= -15.62
3, -6/10= -12/20, 3/4= 15/20, -12/20+15/20= 3/20
4, 56.27+(-13.16)= 43.11
5, 3.5+12.4= 15.9, 4/5= 0.8, 15.9+0.8= 16.7
Fraction form:
-15.62=1562/100= 15 62/100= 15 31/50
43.11= 4311/100= 43 11/100
16.7= 167/100= 1 67/100
1/4= 25/100
3/20= 15/100
25/100=
15 62/100=
43 11/100=
1 67/100
or
1/4=
15 13/50=
43 11/100=
1 67/100
Decimal form:
1/4=0.25
3/20=0.15
0.25=
-15.62=
0.15=
43.11=
16.7
(i don't know which form you needed so this is fraction simplify and decimal simplify forms, the bold ones are and the un-bold one was the steps)
