Hello

Simplify to a simplified fraction

1/2+1/3+1/4+1/5+1/6+1/7+1/8+1/9+1/10

= 5/10 + 2/6 + 2/8 + 2/10 + 1/6 + 1/7 + 1/8 + 1/9 + 1/10

= 8/10 + 3/6 + 3/8 + 1/7 + 1/9

= 24/30 + 15/30 + 21/56 + 8/56 + 1/9

= 39/30 + 29/56 + 1/9

= 117/90 + 29/56 + 10/90

= 127/90 + 29/56

= 3556/2520 + 1305/2520

= 4861/2520

Find the ratio y:x, if 3x=11y,

Aleks [24]

Answer:

3:11

Step-by-step explanation:

3x=11y

Rearrange to the format of the ratio.

11y = 3x

Let's find y/x. y/x is y:x.

11y = 3x

Divide both sides by 11.

11y/11 = 3x/11

y = 3x/11

NOW LET'S DIVIDE BOTH SIDES BY x TO GET x AS THE DENOMINATOR OF y.

y = 3x/11

y/x = (3x/11)/x

y/x = (3x/11) * 1/x

y/x = 3/11

Therefore, y:x = 3:11

Please thank, rate 5 stars, and give brainliest. Thank you.
