Answer:
Calculate the percent value:
0.942 =
0.942 × 100/100 =
(0.942 × 100)/100 =
94.2/100 =
94.2%;
In other words:
1) Multiply that number by 100.
2) Add the percent sign % to it.
Answer:
0.942 = 94.2%
Step-by-step explanation:
Let x be the unknown number
x×55%=121
x=121÷55%
x=220
So 121 is 55% of 220
So k=katie's' age
m=mara's age
k is 2 times as old as m
k=2m
sum is 24
add means sum
k+m=24
so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16
katie=16
mara=8
Whats the problem? i cant solve it w/o the problem doll
