1/7 / 4 as a fraction

Answers

1/7/4 is a fraction.

1/7 divided by 4 is equal to 1/28.

Given that a fraction, we need to make it in proper fraction,

To divide fractions, you need to follow a specific rule. To divide one fraction by another, you multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is obtained by interchanging the numerator and the denominator.

In this case, you have the fraction 1/7 divided by 4. To find the result, we can express 4 as a fraction with a denominator of 1: 4 can be written as 4/1.

Now, we can multiply the first fraction (1/7) by the reciprocal of the second fraction (4/1):

(1/7) x (1/4)

To multiply fractions, you simply multiply the numerators together and the denominators together:

(1 x 1) / (7 x 4)

The result is:

1/28

Therefore, 1/7 divided by 4 is equal to 1/28.

Answer:

130356 grams.

Step-by-step explanation:

The table shown in the picture is a proportion table. What I did here was divide 34932 by 4.1. That gave me 8520. So, 1 cm³ of metal is 8520 grams. Now multiply that by 15.3.

8520/1 * 153/10

Cross-cancellation (8520 becomes 852, 10 becomes 1 (GCF: 10))

852 * 153

Multiply 852 by 153 to get 130356.

130356

15.3 cm³ of metal weighs 130,356 grams.

Answer: Yellow flowers 3 1/3 And red flowers 7

Step-by-step explanation:

So you take 3 and put into 1/3. You get 3 1/3 because if you multiply them together you get 21 and there's 21 yellow flowers in total. Then for "R" (red flowers) you would divide 21 by 3 (the reason you divided it by 3 is because there's 3 times the number of red flowers.) you would get 7.

Yellow Flowers: 3 1/3

Red Flowers: 7

yellow flowers are 3 and a half and red flowers is 7 ;)
