There are 3 simple steps to subtract fractions

1. Make sure the bottom numbers (the denominators) are the same.

2. Subtract the top numbers (the numerators). Put the answer over the same denominator.

3. Simplify the fraction (if needed).

1. 2 8/7 - 2 1/7 = ?

2 - 2 = 0

8 - 1 = 7

The fraction is 7/7. 7/7 is the same as 1.

0 + 1 = 1

2. 8 12/31 + 4 5/6 = 13.2204301075

13.2204301075 ≈ 13

3. 15 2/15 - 15 1/20

0.08333333333 ≈ 1

Hector is competing in a 42 mile bicycle race, he has already completed 18 miles of the race ad is traveling at a constant speed

kkurt [141]

Time it took Hector to complete 18 miles is given by 18 / 12 = 1.5 hours.

Let the time when Wanda will catch up to Hector be t, then, the distance covered by Hector at the time they meet is 18 + 12t and the distance covered by Wanda at the time they meet is 16t.

Then, 18 + 12t = 16t
16t - 12t = 18
4t = 18
t = 18 / 4 = 4.5

Therefore, Wanda will catch up with Hector after 4.5 hours.

A spaceship is traveling at a steady rate. The table shows the distance the spaceship travels in a given period of time. Find th

nika2105 [10]

The distance of the spaceship in discuss as in the task content given can be evaluated as; 800miles.

<h3>What is the distance the spaceship travels in 4 minutes?</h3>

The distance travelled by the spaceship in discuss can be evaluated by means of the slope of the linear relationship as follows;

Hence it follows from ratios that by observation, the linear relationship has a slope of 200mi/min.

Consequently, we can evaluate the distance travelled after 4 minutes as;

Distance = 200 × 4 = 800mi.

Ultimately, the distance travelled per minute by the spaceship is; 800mi.

Remarks:

600 miles

520 miles

800 miles

1,080 miles
