    Answer:

    Step-by-step explanation:

    \frac{5}{6}=\frac{15}{18}

    Cross multiply

    5 *18 = 15 *6

    90  = 90

    True. They are in proportion

    \frac{3}{5}=\frac{60}{100}

    Cross multiply

    3*100 = 60 *5

    300   = 300

    True. They are in proportion

    \frac{20}{14}=\frac{10}{7}

    Cross multiply

    20*7 = 10*14

    140  = 140

    True. They are in proportion

    \frac{4}{13}=\frac{10}{32}

    Cross multiply

    4*32  = 10*13

    128    ≠ 130

    False. They are NOT in proportion

    Answer:

    True

    True

    True

    False

    Step-by-step explanation:

    15/18 simplified is 5/6

    3/5 multiply both numerator and denominator by 20 to get 60/100

    20/14 simplified is 10/7

    4/13 multiply both by 2.5 to get 10/32.5 and 32.5 does not equal 32
