C  =      5    9    (  F  −  22  )a)       34    ∘    F   to celsiusWe know that   c  =      5    9    (  F  −  22  )    F  =  34    ∴  c  =      5    9    (  34  −  32  )    =      5    9    (  34  −  32  )    =      5    9    ×  =      10    9    =  1.111111    ≈  1.1So,       34    ∘    F  =      1.1    ∘    Cb)   −      70    ∘   to celsius So,   c  =      5    9    (  F  −  32  )    =      5    9    (  −  70  −  32  )    =      5    9    ×  −  102  =  −            5      x      ×      102        9      =            −      5      ×      34        3      =            −      170        3    =  −  56.666    ≈  −  56.67    ≈  −  56.7So,   −      70    ∘    F  =  −      56.7    ∘    Cc)       25    ∘     to Fahrenheit    c  =      5    9    (  F  −  32  )    =&amp;gt;  9  c  =  5  (  F  −  32  )    =&amp;gt;            9      c        5    =  F  −  32    =&amp;gt;  F  =            9      c        5    +  32    c  =      25    ∘  So,   F  =            9      ×      25        5    +  32    =  45  +  32    =      77    ∘      ∴      25    ∘    =      77    ∘    F
