What's the result of the comparison between 5 / 3 of a kilogram and 5 / 1 of 3000 grams

3/5:(3*1/5)
=3/5:3/5
=1:1
equal

Three fifths of a kilogram is as heavy as one fifths of a three kilogram

The same size

A kilogram of flour is heavier than a kilogram of cotton______ (judge right or wrong)

A kilogram of flour is as heavy as a kilogram of cotton

The solution of the equation half m + one third M = 5-One sixth is
A.m=10 B.m=15 C.m=30 D.m=5
The solution of half m + one third M = 5-One sixth M

The solution of the equation half m + one third M = 5-One sixth is as follows:
One half m + one third M = 5-One Sixth
3m+2m=30-1
5m=29
m=29\5
The question is wrong. Please check it

A kilogram of iron weighs more than a kilogram of cotton______ (judge right or wrong)

Because 1kg = 1kg, 1kg of iron is as heavy as 1kg of cotton, so 1kg of iron is heavier than 1kg of cotton

If x = - 2 is the solution of the equation a (x + 1) = one sixth (a + x), find the value of a & sup2; - half a

Take x = - 2 into a (x + 1) = one sixth (a + x)
Find a = two fifths
Then the value of a is brought into the required problem to find out its value

Five thousandth of seven grams of soybean oil, five thousandth of eight grams, how many kilograms of oil can be extracted from one kilogram of soybean, and how much oil is needed to extract one kilogram of soybean oil

One kilogram of soybean can extract a kilogram of oil
1：a=5/7：5/8
5/7a=5/8
A = 7 / 8 kg
It takes a kilogram of soybeans to squeeze one kilogram of oil
5/7：5/8=b：1
5/8b=5/7
B = 8 / 7 kg
It takes 8 / 7 kg of soybeans

One third x = one half x, x =?
As above

0.

Is four ninths of a kilogram equal to one ninth of four thousand grams?

Yes, absolutely
