To find 3/7 of Julian's number, we first determine his number by solving the equation (2/3) * J = 42, which gives us J = 63. Then, we multiply J by 3/7 to get the final answer: 3/7 of Julian's number is 27.
Step-by-step explanation:
To find 3/7 of Julian's number, we start by finding the whole number, which we'll call 'J'. Julian's number has been partially defined as 2/3 of J equals 42. To find J, we can set up the equation (2/3) * J = 42. Solving for J, we get J = 42 / (2/3). This simplifies to J = 42 * (3/2) = 63. Now that we know J is 63, we can calculate 3/7 of Julian's number.
To do that, we multiply J by 3/7, so (3/7) * 63. We know that 63 is divisible by 7, which makes our calculation simpler. (3/7) * 63 = 3 * (63/7) = 3 * 9 = 27. Therefore, 3/7 of Julian's number is 27.
The probable question can be: Julian thinks of a number. 2/3 of Julian’s number is 42 Work out 3/7 of Julian’s number.
