    5. answer = 315 r 2
    6. answer = 23925
    7. answer = 9479
    8. answer = 2677

  2. 1)7+4+2+4+7+5+10+3+3=46 46%9=5r1 mean=5.1
    2)17+20+2+16+2+3=60 60%6=10 mean=10
    3)19+30+25+14=88 88%4=22 mean=22
    4)2+3+3+5+— mean=3
    I do not get (4)

  3. 1.) mean = 5 2.) mean = 10 3.) mean = 22 4.) missing number = 2

    back to basics:
    5.) 357 r3 6.)435 x 55 = 23,925 7.) 4,364 + 5,115 = 9,479
