To find the number of cups of flour, we need to set up a proportion using the ratio given.
The given ratio is:
1/3 teaspoon of salt / 3/4 cup of flour
Let x be the number of cups of flour needed.
So, we can set up the proportion:
1/3 teaspoon of salt / 3/4 cup of flour = 1 teaspoon of salt / x cups of flour
To solve for x, we can cross multiply:
(1/3) * x = (3/4) * 1
x/3 = 3/4
To isolate x, we can multiply both sides of the equation by 3:
x = (3/4) * 3
x = 9/4
Converting 9/4 to decimal form, we divide the numerator (9) by the denominator (4):
9 ÷ 4 = 2.25
Therefore, the exact decimal form for the number of cups of flour needed is 2.25.
Find a percent that is equivalent to 15/50.
__%
To find the equivalent percent, we can divide the numerator (15) by the denominator (50) and then multiply by 100.
(15/50) * 100 = 30%
Therefore, 15/50 is equivalent to 30%.
In a bag there are 2 red buttons, 3 green buttons, and 4 purple buttons. A student writes the ratio for the number of purple buttons to green buttons as 3 : 4. Is this student correct? Explain why or why not.
No, the student is not correct.
According to the information given, there are 2 red buttons, 3 green buttons, and 4 purple buttons in the bag.
To write the ratio for the number of purple buttons to green buttons, we divide the number of purple buttons by the number of green buttons.
Ratio of purple buttons to green buttons = Number of purple buttons / Number of green buttons
= 4 / 3
The correct ratio for the number of purple buttons to green buttons is 4:3, not 3:4.
Therefore, the student's statement is incorrect.
