7 because 7 x 7 is 49 but if you add 7 and 7 it gets to 14 7 is the answer
so if you do a different number you will be wrong
You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39
hope it helped
I got 3 quarts... this is the last one I'm doing cause you are mad at me and want nothing to do with me. hope u get the rest of your answers and bye.
