Answer:
Grades 6 and 8
Step-by-step explanation:
If the relationship of girls to boys in two different grades are proportional, <u>they must have the same ratio</u>. To tackle this problem, we can find the <u>ratios</u> of genders in each grade and compare them.
Step 1, finding ratios:
Finding ratios is just like <u>simplifying fractions</u>. We will reduce the numbers by their<u> greatest common factors</u>.
<u>Can't be simplified!</u>

Step 2:
Notice how grades 6 and 8 both had a ratio of 3:4. We can conclude that these two grades have a proportional relationship between girls and boys.

Answer:
- <u><em>A. 6,000 miligrams</em></u>
Explanation:
A <em>balance scale</em> is balanced when the weights on both sides are equal. Then, since the image shows that both sides are equal, the weight of the <em>6-gram weight</em>, placed by Henry on one side of the balance scale is equal to the weight of the <em>ballet slipper </em>placed on the other side.
- Weight of the balance slipper = weight of the 6-gram weight
- Weight of the balance slipper = 6 grams
<u>Conversion of units: </u>
- 6 grams × 1,000miligrams/1gram = 6,000 miligrams
- Weight of the balance slipper = 6,000 miligrams
That is the option A.
Answer:
Step-by-step explanation:
One number would be
9.31
The 3 in this number is 3/10
The 3 in the given number is 3/100
3/10 is 10 times bigger than 3/100
3/10 = 0.3
3/100 = 0.03
0.03 * x = 0.3 Divide both sides by 0.03
0.03/0.03 x = 0.3/0.03
x = 10
