Can three fifths minus three Sevens plus two fifths minus four Sevens be simple?

Can three fifths minus three Sevens plus two fifths minus four Sevens be simple?


Three fifths plus two fifths minus three Sevens minus four sevens. Three Sevens minus four Sevens plus brackets
Equal to 0



One and four fifths minus three Sevens to see the simple calculation of four sevens


1(4/5)-(3/7)-(4/7)
=(9/5)-[(3/7)+(4/7)
=(9/5)-1
=(9-5)/5
=4/5



What is enumeration? Use enumeration to find out the least common multiple 4 and 10, 10 and 5, 8 and 6 of each group


The multiples of 4 are 8, 12, 16, 20, 24, 28, 32, 36 and 40
The multiples of 10 are 20, 30, 40 and 50
So the common multiple of 4 and 10 is 20,40. The smallest is 20, so the least common multiple of 4 and 10 is 20
Same below!
The least common multiple of 10 and 5 is 10,
The least common multiple of 8 and 6 is 24



Find the least common multiple of numbers: 10 and 4 14 and 12 3 and 6 16 and 32 8 and 9 7 and 12
