Plz help, I need help on these couple questions for home work
1. 5 3/8c = ___ fl oz
a: 43 fl oz
B: 43/64 fl oz
C: 86 fl oz
D: 29 fl oz >>>
2. 43 in.= ___ fl
A: 4 1/4 ft. >>>
B 3 ft.
C: 516 ft
D: 3 7/12 ft
3. mi-li has 7 1/2 yd. of material. Her new skirt will take 4 5/8 yd. How much material will she have left after the skirt is made?
2 7/8 yd
2 1/8 yd >>>
3 1/8 yd
3 7/8 yd
a cup is 8 oz
5 3/8 cup * 8 oz/cup = 43/8 * 8 oz = 43 oz
note write conversion so the units you want gone (cup here) cancel
43 in * 1 ft/12 in = ---- ft
etc
7 1/2 - 4 5/8
is
7 4/8 - 4 5/8
is
6 12/8 - 4 5/8
is
2 7/8
Sure, let's go through each question one by one and find the correct answers.
1. 5 3/8c = ___ fl oz
To solve this question, we need to convert cups (c) to fluid ounces (fl oz).
1 cup is equal to 8 fluid ounces.
Therefore, 5 cups would be 5 * 8 = 40 fluid ounces.
Now, let's focus on the fraction 3/8. To convert this fraction to fluid ounces, we need to multiply it by the conversion factor.
1/8 cup is equal to 1 fluid ounce, so 3/8 cup would be 3/8 * 1 = 3/8 fluid ounces.
Adding up the two parts, we get 40 + 3/8 = 40 3/8 fluid ounces.
Looking at the answer choices, we see that the correct answer is D: 29 fl oz.
2. 43 in. = ___ fl
To solve this question, we need to convert inches (in) to fluid ounces (fl).
However, there is no direct conversion between inches and fluid ounces. It seems like there might be a mistake in the question.
Therefore, we cannot determine the correct answer for this question.
3. Mi-li has 7 1/2 yd. of material. Her new skirt will take 4 5/8 yd. How much material will she have left after the skirt is made?
To solve this question, we need to subtract the amount of material used for the skirt from the total amount of material Mi-li has.
First, let's subtract the whole numbers: 7 1/2 yards - 4 5/8 yards.
To do the subtraction, we need a common denominator. The least common denominator for 2 and 8 is 8.
So, 7 1/2 yards can be written as 7 4/8 yards.
Now, subtracting the two fractions: 7 4/8 - 4 5/8 = 3 - 1/8 = 2 7/8 yards.
Therefore, Mi-li will have 2 7/8 yards of material left after making the skirt.
The correct answer is option A: 2 7/8 yd.
I hope this helps! Let me know if you have any other questions.
