Answer:
Step-by-step explanation:
1-124: (convert 1/5 to tenths)
3/10+2/10=5/10 ->1/2
so you have a 1/2 chance of getting blue or green
1-125:
1/2 of the circle is green and 1/4 of the circle is green (1/2 =2/4)
2/4+1/4=3/4 so you have a 3/4 chance of getting purple or green
1-126
a. x+8=21
just minus 8 from x an 21
x=13
b. x-31=55
add 31 to both sides
x=86
c. 3x=54
you are going to divide 3 from both sides
x=18
d. x/5=10
you want to take the reciprocal of x/5 to get rid of x (5/1) and do that to both sides
x=50
Answer: 212.81
C. Since the digit in the thousandths place is greater than or equal to 5, increase the digit in the hundredths place by 1. Then drop the digit in the thousandths place
Step-by-step explanation:
What is 212.809 rounded to the nearest hundredth?
When we want to round off 212.809 to the nearest hundredth, the main thing that we will need to consider is for us to look at the thousandths value that is contained in the number of 212.809, and this is is 9.
Since 9 is more than 5, iteams that we will have to add 1 to the number at the hundredth place. This.meane we will add 1 to 0 which will give us 1 and we them drop the digit in the thousandths place. Therefore,
212.809 = 212.81 to nearest hundredths

Step-by-step explanation:
Just find the number that can divide by the whole. Say the question was
A pet shop have 20 pets. The same amount of pets are in each room. How many rroms could there be?
If there were 4 rooms, 5 pets would be in each. 20÷4=5. 4 goes into 20 so 4 could be an answer.
If there were 3 rooms, 6 rooms would have 3 pets and 2 would be left over. So it wouldn't work. You just need to find the number that goes into the whole with no remainder.
