Answer:
W = 9.33 grams
X = 4.67 grams
Step-by-step explanation:
Given;
Mass of Z to be made = 14 grams
Composition of Z
W:X:Y = 2:1:3
To make 6 grams of Y requires 4 grams of W and 2 grams of X
Composition of Y (for 6grams)
W:X = 4:2 = 2:1
Substituting the composition of Y to Z
Z = W:X:Y = 2:1:3
Z = W:X:W:X = 2:1:2:1
summing them up, we have;
Z = W:X = 4:2 = 2:1
Since the final mixing ratio for W and X are 2:1, to make 14 grams of Z, we need;
W = 2/3 × 14grams = 28/3 grams
W = 9.33 grams
X = 1/3 × 14grams = 14/3 grams
X = 4.67 grams
Just a generic answer would by 12/8 or any other multiple of the numbers. If that is a fraction than same goes as above.
Answer:
2
Step-by-step explanation:
7/3+3(2/3−1/3)^2
=7/3+6/9-3^2/9
=7/3+6/9-9/9
=7/3+2/3-3/3
=6/3
=2
25/4
You can multiply by crossing
10/24 and x/15
10*15 = 24x
150/24=x
Divide the numerator and denominator by 6
25/4
25/4 is the answer
