Hello there! :)
Answer:
1.
2.
Step-by-step explanation:
1. 3/5+4/15
First, you multiply by numerator and denominator.
3*3=9
5*3=15
Then, you had to combine by the fractions.
Add by the numbers from left to right.
9+4=13
<u><em>13/15 is the final answer.</em></u>
______________________________________________
2. 5/6-1/4
First, you multiply by 2 both sides of numerator and denominator.
5*2=10
6*2=12
10/12
3/12
Subtract by the numerator.
10-3=7
<em><u>7/12 is the final answer.</u></em>

Hope this helps!

Step-by-step explanation:
i think?
First we need to find out the volume of one cylinder. We already know the volume of the block of gold is 360cm3
V = Pie * radius squared* height.
Pie is 3.142
radius is 6.18/2 = 3.09 cm
height is 6cm
V = 3.142 * 3.09 * 3.09 * 6
V = 180cm3
Now we divide the volume of this cylinder with the volume of block of gold.
360/180 = 2
So it will take 2 cylinders to mold one block of gold.
