Answer:
30%
Step-by-step explanation:
Since we want percentage, we need to convert 1/4th to percentage first.
We will divide, get decimal, and then multiply by 100 to get percentage.
1/4 = 0.25
0.25 * 100 = 25%
Now, we can say:
45% + 25% + chocolate = 100%
70% + chocolate = 100%
chocolate = 100 - 70 = 30
Chocolate = 30%
The answer would be 21/50. If you have numbers with a few zeros you can cross one of the top amd bottom until you reach the other numbers, if that makes sense. You can changd 420/1000 to 42/100. Then just keep dividing it by a numner that goes evenly into both the numerator and denominator.
3 sides of square is 3*12=36 cm
perimeter for the full circle is 2 * pi * radius
which is =2 * 22/7 * 12 =75.43 cm
so 360° =75.43 cm
for 150° = 75.43/360 *150 =31.43
all together =36 +31.43 =67.43 cm
34 books would be the answer.
