What is the difference in length between a 11/4 inch button and a 3/8 inch button

Mathematics

Answer:

\frac{19}{8}

Step-by-step explanation:

First, multiply the two denominators together to get the shared denominator, which will allow you to actually subtract the two numbers. 4 × 8 = 32, so the shared denominator will be 32.

Then, cross-multiply. 11 × 8 = 88, so \frac{11}{4} becomes \frac{88}{32}. 3 × 4 = 12, so \frac{3}{8} becomes \frac{12}{32}.

Now, you can subtract.  \frac{88}{32} -\frac{12}{32} =\frac{76}{32}

Finally, simplify. \frac{76}{32} =\frac{19}{8}. The final difference is \frac{19}{8}.

Divide the number 480 in a ratio of 3:5
Schach [20]

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).


So divide 480 by 8: 480/8 = 60


Then the ratio is (3x60):(5x60) or 180:300


To check it is correct, add up the two parts to see that they come to 480:


180+300 = 480. All good.


Hope this helps

Sara is collecting signatures to pu on her towns ballot. So far, she has 432 signatures. This is 36% of the number of signatures
In-s [12.5K]

Sara needs to collect 1200 signatures.

Step-by-step explanation:

Let,

x be the total number of signatures she needs to collect

Given percentage = 36%

Signature collected = 432

According of statement;

36% of x = 432

\frac{36}{100}*x=432\\

\frac{36x}{100}=432\\Multiplying\ both\ sides\ by 100\\100*\frac{36x}{100}=432*100\\36x=43200\\Dividing\ both\ sides\ by\ 36\\\frac{36x}{36}=\frac{43200}{36}\\x=1200

Sara needs to collect 1200 signatures.
