Answer:
26 28 and 30
Step-by-step explanation:
we already have the first two as 26 and 28
third = a+5d
= 25+5
=30
( 5/3 + 2 2/5 ) ÷ ( 1 3/4 ) =
( 5×5/3×5 + 2 2×3/5×3 ) ÷ ( 4/4 + 3/4 ) =
( 25/15 + 2 6/15 ) ÷ ( 7/4 ) =
(25/15 + 30/15 + 6/15 ) ÷ ( 7/4 ) =
( 25 + 30 + 6 / 15 ) ÷ ( 7/4 ) =
( 61/15 ) ÷ ( 7/4 ) =
61/15 <em>×</em><em> </em><em>4</em><em>/</em><em>7</em><em> </em> =
61 × 4 / 15 × 7 =
244 / 105
