1-3rd of the flowering plants will have yellow flowers and 1-4th of the flowering plants will have white flowers. what fraction of the flowers will be yellow or white?
1/3 + 1/4 =
4/12 + 3/12 =
7/12
Hey, livelove.....let me show you a quick trick for adding fractions whose denominators are different and whose numerators are 1
Add the denominators....then... multiply the denominators.....then...put the first over the second.....
So...for the above...we have
3 + 4 = 7 and 3 * 4 =12 so we have
7 / 12
You'd have to find the LCD again. Both denominators have the lowest multiple of 12 (4*4 is 12 and 4*3 is 12). Multiply the numerators by the number the denominators were multiplied by (1*3 and 1*4). The final equation would be 3/12*4/12=7/12. 7/12 of the flowers were either yellow or white.
1/3 + 1/4 =
4/12 + 3/12 =
7/12
