Yes 7x22 is 154.
154 sailors. 7:2=x:44 44/2=22 7x22=154
First you need to find the prime factors of 28 and 42. 28= 7x22 42= 7x3x2 Then you multiply 7x3x22, the product of which is 84, which is your answer.
To find the prime factors of a number, it is best to divide them by their obvious divisors. In this case, 28 is prime so can divide by 2. This gives us 14. This is known to be 7x2 from times tables, and so we have finished factorizing 28. The prime factors are 2, 2 and 7. This can be expressed in powers as 7x22.
6,13,27,55, 111, 223 ... Here is why: 6 + (1x7) makes 13 13 + (2x7) makes 27 27 + (4x7) makes 55 55 + (8x7) makes 111 111 + (16x7) makes 223 Or this way explains the answer using powers of 2: (7x20)-1 makes 6 (7x21)-1 makes 13 (7x22)-1 makes 27 (7x23)-1 makes 55 (7x24)-1 makes 111 (7x25)-1 makes 223
(6/6)+(6/6)+(6/6)+6=9
6 - 6 + 6 - 6 + 6 - (6 / 6) = 5
(6-6)*6/6 = 6-6
((6+6)/6)^6 = (12/6)^6 = 2^6 =64
6 + 6 - 6 * 6 - 6 = 6 + 6 - 36 - 6 = -30
6+6+6+6+6+6+6+6+6 =54 This can also be written as 6*9. That is because 6 is added 9 times.
((6+6)/6)^6 = (12/6)^6 = 2^6 =64
