Answer:
the number of grams of zinc contain is 78
Step-by-step explanation:
The computation of the number of grams of zinc contain is shown below:
Given that the ratio of zinc to copper is 3:16
And, the jar of the chemical has 416 grams copper
So, the number of zinc grams would be
here we assume the zinc grams be x
Now the equation would be
3 ÷ 16 = x ÷ 416
Now applied the cross multiplication
16x = 416 × 3
x = (416 × 3) ÷ 16
= 78
Therefore the number of grams of zinc contain is 78
Answer:
Colin and Sarah get 1 - 1/9 = 8/9 of the money
A ratio of 3 :1 means that there are 4 parts of the 8/9....so....each part = 8/9 * 1/4 = 8/36 = 2/9
And Colin gets 3 parts of the 8/9 = 3 * 2/9 = 6/9 = 2/3 of the money
Step-by-step explanation:
Answer:
1. 4.65+3.23 = 7.88 yes
2. 3.23 + 6.42= 9.65 not 9.45 no
3. 2.85 + 3.23 = 6.08 yes
4. 3.23 + 8.49 = 11.72 not 10.72 no
99.10 is the larger answer
