How do you change 7/10 to a percent

2 answers:

8 0

First make the denominator into a 100... to do this you need to multiply the denominator (10) by 10... do the same with the numerator to give you 70. So your percent is 70% because it is a value over 100.

James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The

Brrunno [24]

Answer:

The correct option is 4.

Step-by-step explanation:

Given information:

Bring lunch : 46 males, 254 females

Buy lunch : 176 males, 264 females

Total number of peoples is

$46+254+176+264=740$

Total number of males is

$46+176=222$

The probability of male is

$P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3$

Since probability of males is 0.3, therefore options A and C are incorrect.

Total number of persons who buys lunch is

$176+264=440$

The probability of persons who buys lunch is

$P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}$

We need to find the probability of P(male | buys lunch).

According to the conditional probability, we get

$P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}$

P(male | buys lunch) $=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}$

P(male | buys lunch) $=\frac{\frac{176}{740}}{\frac{22}{37}}$

P(male | buys lunch) $=\frac{2}{5}=0.4$

Therefore the correct option is 4.

25% of 80 = what percent???

Doss [256]

First off, you really don't need to write "what percent???" here.

25% of 80 is 0.25(80) = 20.

Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.

Answer:

2/5 cups oats per cup water
2.5 cups water per cup oats

Step-by-step explanation:

The denominator of the fraction is the unit you want 1 of.

(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)

= (2/5 cups oats)/(1 cup water)

1 cup of water would need 2/5 cups of oats.

Obviously, the other ratio is the reciprocal of this.

(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)

1 cup of oats would need 2.5 cups of water
