How is 7 21/25 written as a decimal
aivan3 [116]
 Im pretty sure the answer is 7.84. i got this because 7 is a whole number so it is in the whole number spot. Then, you have to get your denominator to 100. So, what times 25 equals 100? its 4. so you get 100 so whatever you do to your denominator you do to your numerator. so 21 times 4 is 84. so 84/100 is actually 7.84. Hope this helped

natita [175]
Solve for x:
x/3 + 2/5 = -4
x/3 + 2/5 - 2/5 = -4 - 2/5
x/3 = -22/5
x/3 * 3 = -22/5 * 3
x = -66/5 or -13 1/5
