To solve, convert the mixed number into an improper fraction, multiply (numerators (top numbers) together and denominators (bottom numbers) together) and convert any resultant improper fraction back into a mixed number:
7/8 x 53/7 = 7/8 x (5x7+3)/7
= 7/8 x 38/7
= 7x38/8x7
= 19/4
= 43/4
37/5 : 6*37/6 = 37/5 : 37 = 1/5 : 1 = 1 : 5
5 x 37 = 185
-37
78
37
5 times 37
37
78 as a product of its prime factors is: 2 x 3 x 13 = 78
37 can be expressed as 37 = 5 x 7 + 2, where 5 is the divisor, 7 is the quotient, and 2 is the remainder. Reminder is a positive integer. If you divide 37 by 5 and you get a decimal number 7.4, .4 is not a remainder. Multiply 5 by the quotient 7, and subtract the product 35 from the dividend 37 to get the remainder 2.
45 * 78 = 3510
The product of 78 and 7 is 546
