×85=
5×4=20 carry the 2 about the 2 in 24
5×2=10+ the 2 you carried =120
bring a 0 down under the 0 in 120 cross out the 5
now do 8×4=32 carry the 3 above the two in 24 now
8×2=16+ the 3 carried=19
1120+1920=2,040
Step-by-step explanation:
33/4=8.25
-21/2= -10.5
8.25÷-10.5=0.785
Diana had chocolate, and ate some, leaving 0.75 of it for Sarah.
Sarah ate 18.5 grams of it and return the rest to Diana, which was 65% of the original chococate.
how much chocolate did Diana have at the beginning?
and the solution is:
0.75x-18.50=0.65x
0.75x-0.65x=18.50
0.1x=18.50
x=185
so Diana had 185 grams of chocolate.
