In mathematics and algebra , bracket means product and if two negative numbers are multilplied the answer is always positive.
here, -7 * -3 = 21.
(7 + 7 + 7)/7 = 3
3
7/3
i know that 3:7 is equal to 3/7. to find the percent of 3/7 i need to divide 3 and 7 b/c i need to find the percent. 3/7 as a percent is 42.9% rounded tot he nearest tenth
Put the fractions vertically like this : 3/7 = x/56, then what times 7 is 56, whatever that number is, you would multiply to 3, to get what x equalsIt should be 8(the number you multiply to 3) And you should get... (DO THE MATH)
3
21
If: x+3 = 3+7 Then: x = 7
If 3 ≡ x mod 7, then x = 7k + 3 for some k.
3/7
3/7 is equivalent to the fraction 6/14
7*3= 21
