How do I solve equations with fractions?

ratelena [41]

2y - 3/5 = 1/2

Add 3/5 to both sides.

2y = 1/2 + 3/5

Let's make the two fractions have common denominators.
Multiply 1/2 by 5/5 and 3/5 by 2/2.
1/2 * 5/5 = 5/10
3/5 * 2/2 = 6/10

2y = 5/10 + 6/10

Add the two fractions.

2y = 11/10

Divide both sides by 2.

11/10 ÷ 2
Use the Keep, Change, Flip method.
Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
11/10 × 1/2 = 11/20

y = 11/20

The distance (d) in meters that an ant can travel varies directly with the amount of time (t) in hours it spends walking.assume

san4es73 [151]

Answer:

d = 3 meters

Step-by-step explanation:

d = rt where d is the distance t is the time and r is the constant of proportionality

d = 18t

Changing 10 minutes to hours

10 minutes * 1 hours / 60 minute = 1/6 hour

d = 18 * 1/6 hour

d = 3 meters

Answer:

V=20 in cubed

Step-by-step explanation:

The formula to find the volume of a pyramid is L×W×H÷3

L×W=15 or 5×3=15
15×H=60 or 15×4=60
60÷3=20 in cubed

Therefore V =20 in cubed
