Answer:
i.) 3/5 × ( 10 + 35/24 )
= 3/5 × 10 + 3/5 × 35/24
= 3×2 + 7/8
= 6 + 7/8
= ( 48 + 7 )/8
= 55/8
= 6.875
ii.) 2/3 × ( 7/10 + -3/5 )
= 2/3 × 7/10 + 2/3 + -3/5
= 7/15 + -2/5
= ( 7 - 6 )/15
= 1/15
iii.) 8/7 × ( 6/7 + -3/5 )
= 8/7 × 6/7 + 8/7 × -3/5
= 48/49 + -24/35
= ( 48×5 + -24×7) / 245
= ( 240 - 168 ) / 245
= 72/245
iv.) -2/7 × ( 7/16 - 21/4 )
= -2/7 × 7/16 - -2/7 × 21/4
= -1/8 + 3/2
= ( -1 + 12 ) / 8
= 11/8
