When subtracting fractions with the same denominator (in this case 8) you only have to worry about the numerator (7&3)

ANSWER - 7/8-3/8= 4/8

Now since you can simplify 4/8 you would divide both by 4 and your simplified answer is 1/2.

Keep the denominators the same and subtract the numerators. So for example in your example:

7/8 - 3/8

Leave the 8 alone. Subtract 3 from 7.

7 - 3 = 4

So answer is:

4/8

Sometimes they may have to simplify the answer, and in this case, 4/8 could be simplified to 1/2

Answer:

x = 0.96

Step-by-step explanation:

$7 \times 16^{8x - 8} = 3$

$(2^4)^8(x - 1) = \dfrac{3}{7}$

$2^{32(x - 1)} = \dfrac{3}{7}$

$\log 2^{32(x - 1)} = \log \dfrac{3}{7}$

$32(x - 1)\log 2 = \log 3 - \log 7$

$(x - 1) = \dfrac{\log 3 - \log 7}{32}$

$(x - 1) = \dfrac{\log 3 - \log 7}{32\log 2}$

$x = \dfrac{\log 3 - \log 7}{32\log 2} + 1$

$x = 0.961800237...$

Answer: x = 0.96

In 2002, Takaru Kobyashi ate fifty hot dogs in twelve minutes. At that rate, and assuming that he wouldn’t explode, how many dog

kupik [55]

So he ate 50 in 12 minutes.
There are 60 minutes in an hour. You want to divide 12 into 60 minutes.
Multiply your answer on 5 times the number of Hog-Dogs.
= 250 Hot-Dogs

Three single-digit numbers multiply to make 504 Write the missing numbers

Tom [10]

<span>Find for the 3 single digit number that will be multiplied together to get the product 504.
=> n x n x n = 504 – where n are the single digits that we need to multiply.
504 / 2 = 252
504 / 3 = 168
504 / 4 = 126
504 / 5 = 100.8
504 / 6 = 84
504 / 7 = 72
504 / 8 =63
504 / 9 = 56
Now, let’s have 7 8 9 as 3 numbers to multiply to get 504 as product.
=> 7 x 8 x 9
=> 504
