(1) 4/5 Multipled by 5/7 in simplest form. My answer is 1.9 don't really know if its write show work.
(2) -1 1/6 divided by 2/9= -5 1/4 need help showing work.
(3)-6 2/5 divided by (-2 2/7) = 2 4/5
(4) 2 2/3 divided by (-4 1/4) = -11 1/3 i nedd help showing my work
1.
(4/5)(5/7) = 4/7
2.
-1 1/6 ÷ 2/9
= (-7/6)(9/2) = -63/12 = -21/4 or -5 1/4
3.
(-32/5) ÷ (-16/7)
= (-32/5)(-7/16)
= 14/5 or 2 4/5
4. You do this one the same way I showed you
I need help with my 7th grade math. Can anyone help? It's evaluate the expressions and write them in simplest form. The first question is: -8/3 + 1/4. When u get the answer plz comment and show Me
how u got it. Thanks!!!!!!
Sure! I'll explain how to solve each of these problems step by step:
(1) To multiply fractions, you simply multiply the numerators together and the denominators together. So let's calculate:
(4/5) * (5/7) = (4 * 5) / (5 * 7) = 20/35
To simplify this fraction, find the greatest common divisor (GCD) of both the numerator and the denominator, which is 5 in this case:
20 ÷ 5 / 35 ÷ 5 = 4/7
So the simplified form of 4/5 multiplied by 5/7 is 4/7. Your answer of 1.9 is not correct.
(2) To divide mixed numbers, you first convert them into improper fractions. Let's calculate step by step:
-1 1/6 divided by 2/9
(a) Convert -1 1/6 into an improper fraction:
-1 1/6 = -7/6
(b) Now, divide -7/6 by 2/9:
-7/6 ÷ 2/9
To divide fractions, you multiply the first fraction by the reciprocal (invert) of the second fraction. Let's proceed:
-7/6 * 9/2 = (-7 * 9) / (6 * 2) = -63/12
To simplify this fraction, find the GCD of both the numerator and the denominator, which is 3:
-63 ÷ 3 / 12 ÷ 3 = -21/4
Now, convert the improper fraction into a mixed number:
-21/4 = -5 1/4
So the result of -1 1/6 divided by 2/9 is -5 1/4.
(3) Let's calculate -6 2/5 divided by -2 2/7:
(a) Convert both mixed numbers into improper fractions:
-6 2/5 = -32/5
-2 2/7 = -16/7
(b) Divide -32/5 by -16/7:
-32/5 ÷ -16/7
Again, remember to multiply the first fraction by the reciprocal (invert) of the second fraction:
-32/5 * 7/-16 = (-32 * 7) / (5 * -16) = 224/-80
To simplify this fraction, find the GCD of both the numerator and the denominator, which is 8:
224 ÷ 8 / -80 ÷ 8 = -28/10
Convert the improper fraction into a mixed number:
-28/10 = -2 4/10
Simplify the mixed number by reducing the fraction:
-2 4/10 = -2 2/5
Therefore, -6 2/5 divided by -2 2/7 equals -2 2/5.
(4) Let's calculate 2 2/3 divided by -4 1/4:
(a) Convert both mixed numbers into improper fractions:
2 2/3 = 8/3
-4 1/4 = -17/4
(b) Divide 8/3 by -17/4:
8/3 ÷ -17/4
Again, remember to multiply the first fraction by the reciprocal (invert) of the second fraction:
8/3 * 4/-17 = (8 * 4) / (3 * -17) = 32/-51
To simplify this fraction, find the GCD of both the numerator and the denominator, which is 17:
32 ÷ 17 / -51 ÷ 17 = 32/-51
Convert the improper fraction into a mixed number:
32/-51 = -1 17/51
Therefore, 2 2/3 divided by -4 1/4 equals -1 17/51.
I hope this helps!
