112
There are 28 grams in an ounce and 1000 grams in a kilogram. 28x4= 112 grams divided by 1000 makes it 0.112 kilograms
4 because:- a = missing factor 4 x 7 x a = 28 x 4 28 x a = 112 a = 112/28 a = 4
25% of x=28 0.25x=28 x/4=28 x=28x4 x=112 ;)
To find the common multiples, we first need to break the numbers down into their prime factors: 14 = 2x7 28 = 2x2x7 The next step is to identify any common factors. In this case, both numbers have a single 2 and a single 7, so we can discard one of each. This leaves us with 2, 2 and 7. Multiply these together for the LCM: 2x2x7 = 28 To find other multiples, you now simply multiply this number by any integer. For instance, 28x2, 28x3, 28x4.... Thus the first few common multiples of 14 and 28 are 28, 56, 84, 112.
