Plz help me. I need your help

Step-by-step explanation:

1.

a mother is a she, not a he ...

anyway, we need to make 2/3 and 3/4 comparable.

for this we need to bring both fractions to a common denominator, which is usually the smallest common multiple of the denominators.

yes, 12 is the smallest number that can be divided by 3 and by 4 without remainder.

to transform a fraction too another denominator, we need to multiply it by a fraction a/a, which has the value 1, of course (so we don't change the value of the original fraction), but changes the denominator to the desired number.

what do I multiply with 4 to get 12 ? 3.

so, I multiply 3/4 by 3/3 = 9/12.

what do I multiply with 3 to get 12 ? 4.

so, I multiply 2/3 by 4/4 = 8/12.

now we can compare and calculate :

out of the total of 9/12kg 8/12kg were used.

that means

1/12kg of carrots are left.

2.

this is a strange question, as watermelons, bananas and melons are very differently sized. so, for example 1/2 watermelon and 1/2 banana are very different quantities.

so, what does e.g. 1 fruit mean ?

or if we understand the fractions as shares of the overall smoothie, then we have too much. 4/6 (watermelon) + 2/6 (melon) = 6/6 = 1 (whole smoothie).

so, what to do with the banana ?

this question does not make any sense at all.

but if it is just to add fractions, we can do that :

4/6 + 1/2 + 2/6

as mentioned above, 4/6 + 2/6 = 6/6 = 1

1 + 1/2 = 2/2 + 1/2 = 3/2 = 1.5 or 1 1/2

so there is 1 1/2 fruit in the smoothie (whatever that means).

3.

1 1/2 + 2 1/2 = 2/2 + 1/2 + 4/2 + 1/2 = 8/2 = 4

in total, there are 4 cups of sugar needed.

the solution is 12x-6y

how am i supposed to answer
