im not for sure how to do this but if i get it wrong tell me how to do it correctly
multiply:ex.3/4x1/3 then multiply 3x1 and multiply 4x3 = 3/12 simplifyed to 1/4 would that be correct?
divide:ex.3/4divided by 1/3 then flip second number to 3/1 then multiply 3x3 and 4x1= 9/4 would that be correct?

yes that is correct and then 9/4 since it's an improper fraction would need to be turned into a mixed numer so divide 9 by 4 and you 2 1/4 and a way to tell that this is right is to multiply the 4 times the 2 and add 1 to get 9/4 again so now u know ur mixed number is right.
another example:
3/4 divided by 1/9
flip the 1/9
3/4x9/1=
27/4
6 3/4
6x4+3=27
27/4

including: once you decide on to operate fractions, the denominators (the bottom 1/2 of the fractions) must be an analogous. in the experience that they are, upload the numerators (the suitable 1/2 of the fractions) and positioned that # over the denominator the fractions percentage. celebration- 2/10 + 4/10 = 6/10 If the denominators are distinct, multiply both the numerator and denominator of the fraction(s) so as that the denominators are an analogous. celebration #a million- 2/3 + 2/5 multiply 2*5 and three*5---> new fraction 10/15 multiply 2*3 and three*5---> new fraction 6/15 Then upload like before.... 10/15 + 6/15 = 16/15 or a million a million/15 celebration #2- 4/10 + a million/2 2 must be prolonged by making use of five to get 10, so that you in reality desire to modify the 2d fraction. a million*5 and a couple of*5---> new fraction 5/10 (denominators are an analogous now) 4/10 + 5/10 = 9/10 Subtracting: Subtracting also calls for the denominators to be an analogous. when they are (use the multiplying technique above to assist) you merely subtract the numerators from one yet another. celebration- 6/10 - 2/10 = 4/10 Multiplying: Multiplying is between the finest operations in fractions. All you should do is multiply the numerators by making use of one yet another and the denominators by making use of one yet another (that's typically talked about as 'multiplying for the time of'). it would not count number if the denominators are an analogous once you're multiplying. celebration- 4/6 * 3/5 = 12/30 or 2/5 (2/5 is the simplified version of 12/30). (4*3=12, 6*5=30 ----> 12/30). Dividing: there is not any thanks to really divide fractions, so that you multiply by making use of reciprocals. A reciprocal is (merely) a fragment turn-flopped. Reciprocal Examples- The reciprocal of three/5 is 5/3. The reciprocal of seven/35 is 35/7. The reciprocal of 10 is a million/10 (undergo in ideas 10 is a fragment- it really is 10/a million). The reciprocal of sixty 4 is a million/sixty 4. Dividing/multiplying by making use of reciprocal examples- ( ' / ' stands for divided by making use of) 2/10 / 3/5 ---> (multiply by making use of reciprocal) ameliorations to... 2/10 * 5/3 (then multiply the fractions) 2*5 and 10*3 ---> 10/30 or a million/3 6/30 / 2/12 ---> (multiply by making use of reciprocal) ameliorations to... 6/30 * 12/2 (then multiply the fractions------- 12/2 equals 6) 6/30 * 6.... 6*6 and 30*a million-----> 36/30 i understand all of it sounds complicated yet merely practice it slightly and also you may understand very immediately. i am hoping this facilitates! solid luck on your try!

Yes you are correct.
Also, you would usually take simplify the 9/4 to 2 1/4 as the final step.
