For multiplication, just multiply the numerators (top number) together, and the denominators (bottom number) together. For division, use the “Keep it, Change it, Flip it” method. KEEP the first fraction as it is. CHANGE the division sign into a multiplication sign. FLIP the second fraction (I.e, write it’s reciprocal), then all you have to do is multiply, and it will make it much easier! Hope this helps!!
