numben between 8/5 and 7/3​

Answer 1

Step-by-step explanation:

(i) 536+642i 536+642

At first, we will calculate the LCM of 36 and 42. The prime factorisation is 36 and 42 is,

36 = 2 × 2 × 3 × 3

42 = 2 × 3 × 7

Now, LCM of 36 and 42 = 2 × 2 × 3 × 3 × 7 = 252

536+642=5×736×7+6×642×6=35252+36252=35+36252=71252536+642=5×736×7+6×642×6=35252+36252=35+36252=71252

(ii) 123+245=1×3+23+2×5+45=53+145ii 123+245=1×3+23+2×5+45=53+145

Now, LCM of 3 and 5 is 15.

53+145=5×53×5+14×35×3=2515+4215=6715=4715
