a.Find three different ratios that are equivalent to the ratio .
b.Explain why your ratios are equivalent.

Answers

Step-by-step explanation:

a.14.6. b.when u multiply both part of ratio by the same number you make ur ratio....so we we're dealing with a ratio,if we r multiplying or(dividing)both part of it's by the same number we are creating equal ratio

Answer:

EXAMPLE: 2,3 = 4,6 = 6,9

Step-by-step explanation:

THESE ARE ALL EQUIVALENT BECAUSE... you are just multiplying each number by the same factor. 2x2=4 and 3x2=6 this gives me the next ratio of 4,6. But only multiply the first given ratio to find the next.

Jerri was using a recipe for a large cake that required one-fourth of a tablespoon of cinnamon. Instead of making one large cake, Jerri decided to use the recipe to make three small cakes. How much cinnamon should she use for each of the three small small cakes?

Answers

Im pretty sure you would put 1/12 tablespoon of cinnamon in the cakes individually. You would divide 1/4 by 3. It's pretty simple. If that's not the answer I apologize dearly!

Answer:

1/12 of cinnamon

Step-by-step explanation:

14 divided by 3= 1/12 in fraction form

Juan and Gloria are comparing the two numbers 354.6 and 354.06. Juan says that 354.06 is equal to 10 x 354.6. Gloria says he is wrong. Do you agree with Juan or Gloria? Explain your thinking.

Answers

I agree with Gloria because Juan’s answer would be 3546.6. If you multiply any number by 10 it is moving to decimal 1 place to the right so as an example 354.06 multiplied by 10 would be 3540.6 because you moved the decimal to the right one number.

Juan is incorrect; Gloria is right. 354.06 is not equal to 10 times 354.6 as the zero only changes the decimal place value.

Gloria is accurate while Juan is mistaken. 354.6 and 354.06 do not add up to the same number. It is not possible to get a value that is 10 times the other number (354.6) by adding a zero to the decimal point (354.06).

Only the decimal place value is altered when a zero is added the actual numerical value remains unchanged. Compared to 354.6, which only has one decimal place, 354.06's additional zero after the decimal point indicates a more accurate measurement. Juan was mistaken when he said that 354.06 was equal to 10 times 354.6.

Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 +40. Her work is shown below.

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

84 + 40 = 2 (42 + 20)
