In english it is very common for vowells to be silent, or ignored. usually this is because they are making another vowell make a sound but this isn't always the case. Some example words could be Giraffe (e is silent) and Rules (the e makes the u make a sound but if it weren't for english rules, could be taken out.) Business also works (we don't say the i)
Answer: 7/12
Explanation: To add these two fractions together, we start by finding their common denominator. The common denominator for 3 and 4 is 12.
So we multiply top and bottom of our first fraction by 4 and top and bottom of our second fraction by 3.
That gives us 4/12 + 3/12 which simplifies to 7/12.
