Fractions
By Your Name
Adding and Subtracting
This is how you add and subtract factions...
In order to add or subtract a faction, you first need to check the denominator, otherwise known as the bottom number. If the denominator is same, add or subtract the top number, the numerator. Example: 3/8+4/8=7/8. Now if the denominator isn't same, you need to multiply until you find a common denominator. Example: 2/12+(4/6x2)=8/12
Now on to Dividing and Multiplying
In order to multiply Fractions you need only to multiply the numerator and denominator by the other numerator and denominator. Example: 2/9x3/2=6/18. Now dividing is a little harder, but all you need to remember is Keep,Change,Flip. Keep the first number, change the division symbol to a multiplication symbol, and flip the last number. Example: 6/8 [➗▶️✖️](4/3▶️3/4)=18/32.
Adding and Subtracing Decimals
In order to add and subtract decimals, you girl need to imagine the decimal isn't there. The add or subtract as normal, and re-add the decimal.
Multiplying and Dividing
Multiplying and Dividing decimals are the exact same technique as Adding and Subtracting. Imagine there is no decimal, complete the problem, and re-add the decimal.
