Since the 4 sectors of the spinner are equal, the probability of spinning any one of them is 1/4. Coins are always 50/50, so the probability of tossing a head with a penny is 1/2. Since the question is spinning C AND tossing a head with a penny, you must multiply the two previously found probabilities. 1/4 times 1/2=1/8 so 1/8 is the answer.
It is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.

Division of whole numbers</h3>
When the numerator and denominator of improper fractions are in whole number form, it makes the division a lot easier.
<u>For example</u>;
what is the simplest form of 0.1/0.2?
To obtain the simplest form of the above function, we multiple the numerator and denominator by 10.
= (0.1 x 10)/(10 x 0.2)
= 1/2
<u>Note:</u> introducing factor of 10 to both numerator and denominator has not changed the function.
Thus, it is important to multiply the dividend and the divisor by the same power of 10 to remove the decimal point.

Answer:
Step-by-step explanation:
a) We're working with the ratio 3:1
x:500
500/1 = 500
500 * 3 = 1,500
x = 1,500
She would need to use 1,500 mL of yellow ink.
b) We're working with the ratio 2:3
x:750
750/3 = 250
250 * 2 = 500
x = 500
She would need to use 500 mL of red ink.
You can check both of these by:
(a) 1,500/500 = 3/1 = 3 : 1 which is the ratio we're working with.
(b) 500/2 = 250
750/2 = 375
250 : 375
Then, divide both 250 and 375 by 125
250/125 = 2
375/125 = 3
We are then left with the ratio 2 : 3 which is the ratio we're working with.
