Find the difference in simplest form for 3/5-1/7

Mathematics
1 answer:
vitfil [10]3 years ago

3/5 - 1/7

Find the LCM of 5 and 7 to find equivalent fractions for both fractions

LCM = 35

3/5 = 21/35

1/7 = 5/35

So 21/35 - 5/35 = 16/35

I'm pretty sure that's the simplest form because I can't think of a common factor of 16 and 35 by which to reduce it further.

Levart [38]

Answer:

Subtracting 7

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Clara is stacking cups; she put 45 plastic cups in the first stack, 38 plastic cups in the second stack, 31 plastic cups in the third stack, and 24 plastic cups in the fourth stack. </em>

<u><em>To Find:</em></u>

<em>What kind of sequence is this?</em>

<u><em>Solve:</em></u>

<em>Let's make a table:</em>

<em />

<em>[1 stack]  45 </em>

<em>[2 stack] 38</em>

<em>[3 stack] 31</em>

<em>[4 stack] 24</em>

<em />

<em>Now all we have to do is subtract to see what each is:</em>

<em>45 - 38 = 7</em>

<em>38 - 31 = 7</em>

<em>31 - 24 = 7</em>

<em>Thus,</em>

<em>[1 stack]  45 ⇒ 7</em>

<em>[2 stack] 38 ⇒ 7 </em>

<em>[3 stack] 31 ⇒ 7 </em>

<em>[4 stack] 24 ⇒ 7 </em>

<em>Hence, each stack is going down by 7.</em>

For what values of x is the following equation satisfied : 3x+9 = 21+7x ?
olya-2409 [2.1K]
First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.

You said that <span><u>3x+9 = 21+7x </u>

Subtract 3x from each side:

9 = 21 + 4x

Subtract 21 from each side:

-12 = 4x

Divide each side by 4 :

<u>-3 = x </u>
</span>
