The expression (27 \times 15) can be calculated as follows: (27 \times 15 = 405). Thus, an equivalent expression is simply (405). Alternatively, it can also be expressed in terms of its factors, such as (3^3 \times 3 \times 5), which simplifies to (3^4 \times 5).
Three quarters is equivalent to nine twelfths. This is calculated by multiplying the numerator and denominator of the fraction ( \frac{3}{4} ) by 3, resulting in ( \frac{3 \times 3}{4 \times 3} = \frac{9}{12} ).
2 x 2/3 is equivalent to 4/3.
To calculate (0.15 \times 10 \times 10 \times 10), you can simplify it as (0.15 \times 10^3). Since (10^3 = 1000), the calculation becomes (0.15 \times 1000), which equals (150). Therefore, the equivalent number is (150).
6.17*10^3 is equivalent to 6170

2/8 = 1/4 3 times 2/8 = 3*1/4 = 3/4
Umm, no. Two thirds and six ninths are equivalent. They look like this 2/3 and 6/9, to get to 9 you times the 3 by 3 so to get the 6 you have to times the 2 by 3. I can see that you've seen that you have squared 3 so you had to square 2, but unfortunately that isn't what happens.
The volume is 12cm because 2 times 3 times 2 is equivalent to 12.
this is how you find equivalent fractions... OK if you have 3 8th as a fraction, you can times 8 by 2 and get sixteen. what ever you do to the bottom you do to the top. so you also times 3 by 2 and get 6. your new fraction is 6 16th. get it? you can times the number by any other number. but i say times it by 2 because it's easier:)
2/6, 3/9, any fraction where the denominator is three times the numerator
1/4 = 0.25 3/10 = 0.3 1.25 times. 0.25 * 1.25 = 0.3
times the denominator (bottom part), and whatever you do with the bottom you do with the top
