How do you subtract (2/3)-(1/6)
kakasveta [241]
What is 2/3 - 1/6?<span><span>Here's how to subtract 1/6 from 2/3:<span><span>23</span>−<span>16</span></span></span><span>Step 1We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.So we multiply 2 by 6, and get 12.Then we multiply 1 by 3, and get 3.Next we give both terms new denominators -- 3 × 6 = 18.So now our fractions look like this:<span><span>1218</span>−<span>318</span></span></span><span>Step 2Since our denominators match, we can subtract the numerators.12 − 3 = 9So the answer is:<span>918</span></span><span>Step 3Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?To find out, we try dividing it by 2...Nope! So now we try the next greatest prime number, 3...Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:<span><span>918</span>÷ 3 =<span>36</span></span>Let's try dividing by 3 again...Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:<span><span>36</span>÷ 3 =<span>12</span></span>Let's try dividing by 3 again...No good. 3 is larger than 1. So we're done reducing.There you have it! The final answer is:<span><span>23</span>−<span>16</span>=<span><span>12</span></span></span></span></span>There are 3 simple steps to subtract fractions<span>Make sure the bottom numbers (the denominators) are the same.Subtract the top numbers (the numerators). Put the answer over the same denominator.<span>Simplify the fraction (if needed).

Winton was givin $14 to spend at a school fair he spent 3/7 playing games how much money is lift
Ksivusya [100]
<h3><u>Question:</u></h3>

Winton was given $14 to spend at a school fair he spent 3/7 playing games how much money is left

<h3><u>Answer:</u></h3>

Amount left with winton is $ 8

<h3><u>Solution:</u></h3>

Given that Winton was given $14 to spend at a school fair

He spent \frac{3}{7} playing games

To find: money left with Winton

From given information,

Money given to Winton = $ 14

Amount spent on games = \frac{3}{7}

Thus we can say,

Amount spend on games = \frac{3}{7} of total money he has

\rightarrow \frac{3}{7} \times 14 = 3 \times 2 = 6

Thus he spend $ 6 on playing games

<em><u>Money left with Winton:</u></em>

Money left = total money he had - money spent on playing games

Money left = 14 - 6 = 8

Thus amount left with winton is $ 8
