1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2
Answer:

Step-by-step explanation:
we know that
To find out how much solution the scientist used for the experiment multiply 3/4 by 1/6

simplify

Answer:
11/9 or 1 2/9
Step-by-step explanation:
2/3 multiples by 3 in both the numerator and denominator is equal to 6/9. 6/9 plus 5/9 is 11/9. you want to make sure the denominator is the same before adding or subtracting
Step-by-step explanation:
I'm not sure what you mean by 'written method' but the sum is 2,654.
Answer: The answer is 14
Step-by-step explanation:
For 2.5 they multiplied by 10 so you'd do that for 1.4 and the answer would be 14
